+++[ejemplo de PL en en notación matricial]
Esta es una prueba de programación lineal en formato matricial "abreviado":
`min Z(x)=c^T*x`
`s.t.:`
`A*x<=b`
`x>=0`
`x=0`
+++[Ahora en formato matricial explícito:]
`min Z(x)=[c_1,c_2,"...",c_n]*[(x_1),(x_2),(":"),(x_n)]`
`s.t.:`
`[(a_11,a_12,"...",a_1n),(a_21,a_22,"...",a_2n),(":",":","...",":"),(a_m1,a_m2,"...",a_mn)]_(mxn)*[(x_1),(x_2),(":"),(x_n)]<=[(b_1),(b_2),(":"),(b_m)]`
`[(x_1),(x_2),(":"),(x_n)]>=0`===

ASCIIMathML.js
==============
This file contains JavaScript functions to convert ASCII math notation
to Presentation MathML. The conversion is done while the (X)HTML page
loads, and should work with Firefox/Mozilla/Netscape 7+ and Internet
Explorer 6+MathPlayer (http://www.dessci.com/en/products/mathplayer/).
Just add the next line to your (X)HTML page with this file in the same folder:
<script type="text/javascript" src="ASCIIMathML.js"></script>
This is a convenient and inexpensive solution for authoring MathML.

/* ASCIIsvg.js
==============
JavaScript routines to dynamically generate Scalable Vector Graphics
using a mathematical xy-coordinate system (y increases upwards) and
very intuitive JavaScript commands (no programming experience required).
ASCIIsvg.js is good for learning math and illustrating online math texts.
Works with Internet Explorer+Adobe SVGviewer and SVG enabled Mozilla/Firefox.

!Basic TiddlyWiki notions
*A chunk of data, like the one you are viewing now is called a tiddler. It consists of a title, a text body, tags (to be used to find similar tiddlers and group them), fields for storing data with the tiddler of any kind, and modifier with dates.
*Clicking on a blue link opens up the tiddler or closes it if it is open (depending on settings).
*Double clicking a tiddler shows the code for the tiddler. If you cannot edit it, go to AdvancedOptions and click Edit while HTTPing. This is to prevent you from making changes and not being able to save them.
*The whole system is called TiddlyWiki and http://www.tiddlywiki.com is the home of the original and a great jumping off point to learn more.
!Basic syntax common to all TW's and generally wikis
*There is a lot to practice with. Two single quotes on the left and two on the right ''bold'' the quantity surrounded.
*To italicize use slashes //italics// {{{//italics// }}}
*Tables are done with vertical bars separating columns:
|hi|first|table|
| hi| first |table |
Type:
{{{
|hi|first| table|
| hi| first |table |
}}}
Spaces are critical near the bars for changing behavior.
*Highlighting and general CSS styling are accomplished by pairs of double at signs: @@high@@ or @@font-size:2em;high@@ Type: {{{@@high@@ or @@font-size:2em;high@@}}}
*Bullet lists and numbered lists are done with asterisks and number signs at beginning of line
**Nested is okay {{{*Bullet lists and numbered lists are done with asterisks and number signs at beginning of line
**Nested is okay
}}}
*Headings are done with exclamations at the beginning of a line. One is the largest, 5 is the smallest, I believe.
*Links are either done with WikiWords or done by using double square brackets [[Sample Link]].
*No doubt much more such as __this__ or --this-- or even slides and tooltips and images and and and
*Plugins extend this system and there are a lot of amazing ones out there.
!AsciiMath
*adapted from Peter Jipsen's AsciiMath.
*To do mathematics, first get FireFox. It can be done in IE and that is on my list, but it is a pain and not very good looking. FireFox 1.5.+ or 2.+ are good. You may need fonts from http://www.mozilla.org/projects/mathml/fonts/
*To do math, use a single backtick, followed by a math expression, followed by another backtick. While styling is doable, that is not quite nicely dealt with yet. Ditto with displaying centered math. But soon.
*Simple: `x^2 + 3x = 5` Type:{{{ `x^2 + 3x = 5` }}}
*Calculus: `(d [int_0^x f(t) dt ])/(dx) = f(x)` Type:{{{ `(d [int_0^x f(t) dt ])/(dx) = f(x)` }}}
*Functions: `sin(x)/cos(x)=tan(x)` and `e^(ix) = cos(x) + i sin(x)` and `log_3(x)` `root 3 4` Type: {{{`sin(x)/cos(x)=tan(x)` and `e^(ix) = cos(x) + i sin(x)` and `log_3(x)` `root 3 4`}}}
*Matrices: `[(3,4, 6),(3/4, int_3^4 theta d theta, sqrt(a_34^56))]` Type: {{{`[(3,4, 6),(3/4, int_3^4 theta d theta, sqrt(a_34^56))]`}}}
*Symbols: `Sigma sigma odot oplus otimes in nn cup cap delta del omega psi` Type: {{{`Sigma sigma odot oplus otimes in nn cup cap delta del omega psi` }}}
!AsciiSVG
*adapted from Peter Jipsen's AsciiSVG
*To draw pictures, use 2 backticks on either side. This is a full javascript environment, so be careful.
*See [[Sample Pictures]] for lots of static examples. Code included in viewpoint.
*See InteractiveGallery for a baby step taste of what can be done.

Una compañía producie regalos caros y poco comunes para su venta. Se necesita decidir si es recomendable producirlo, y de hacerlo, en qué cantidad. Se obtendrá un pronóstico para calcular cuántos pueden ser vendidos en el mercado. Se desea tomar una decisión que maximice las ganancias.
El costo fijo en que se incurre si se decide producir, es de 50.000 dólares. Este costo no se tendría, si se decide no producir.
El costo de producción (variable) es de 400 dólares por cada producto fabricado. Cada producto puede venderse en 900 dólares.
Construya una hoja de excel que permita apoyar en la toma de esta decisión. Se debe poder utilizar una celda en la que se coloca una cantidad de producción hipotética, y en otra celda debe indicarse la ganancia/pérdida calculada para cada caso de forma automática.

(Deben descargar el Add-in e instalarlo en excel)
Varias acotaciones:
1) Debe haber 2 actividades "extra", la "start" y la "end".
2) En esas actividades extra, ... no colocar precedentes, ni tiempos
de duración mínimo, probable (likely) ni máximo.
3) Coloquen que la duración de los proyectos es "Random".
4) Desactiven las casillas de "Cash Flow" y "Random Data".
Una vez hayan presionado "Solve", en la columna a la derecha de los
botones tendrán información importante respecto a la fecha de
culminación del proyecto:
Critical = esperanza de ocurrencia del final del proyecto.
Var. = Varianza del momento de finalización del proyecto.
SD = Desviación estándar del momento de finalización del proyecto.
Prob = probabilidad de terminar el proyecto en la el momento que
ustedes hayan colocado en la celda "Due".
Las demás son de menos importancia. Por lo tanto, para encontrar el
día o la semana en la que se puede culminar el proyecto con 80% de
probabilidad, es cosa de "tantear" colocando números en la casilla
descrita como "Due". Noten, que si colocan como numero, exactamente el
que les da la casilla de "Critical", la probabilidad de 0,5.
Eso es porque estarían calculando la probabilidad de culminar
exactamente en la fecha de la esperanza de finalización del proyecto
(y esta se distribuye como una curva normal).

Insert Javascript executable code directly into your tiddler content. Lets you ''call directly into TW core utility routines, define new functions, calculate values, add dynamically-generated TiddlyWiki-formatted output'' into tiddler content, or perform any other programmatic actions each time the tiddler is rendered.
!!!!!Usage
<<<
When installed, this plugin adds new wiki syntax for surrounding tiddler content with {{{<script>}}} and {{{</script>}}} markers, so that it can be treated as embedded javascript and executed each time the tiddler is rendered.
''Deferred execution from an 'onClick' link''
By including a label="..." parameter in the initial {{{<script>}}} marker, the plugin will create a link to an 'onclick' script that will only be executed when that specific link is clicked, rather than running the script each time the tiddler is rendered.
''External script source files:''
You can also load javascript from an external source URL, by including a src="..." parameter in the initial {{{<script>}}} marker (e.g., {{{<script src="demo.js"></script>}}}). This is particularly useful when incorporating third-party javascript libraries for use in custom extensions and plugins. The 'foreign' javascript code remains isolated in a separate file that can be easily replaced whenever an updated library file becomes available.
''Display script source in tiddler output''
By including the keyword parameter "show", in the initial {{{<script>}}} marker, the plugin will include the script source code in the output that it displays in the tiddler.
''Defining javascript functions and libraries:''
Although the external javascript file is loaded while the tiddler content is being rendered, any functions it defines will not be available for use until //after// the rendering has been completed. Thus, you cannot load a library and //immediately// use it's functions within the same tiddler. However, once that tiddler has been loaded, the library functions can be freely used in any tiddler (even the one in which it was initially loaded).
To ensure that your javascript functions are always available when needed, you should load the libraries from a tiddler that will be rendered as soon as your TiddlyWiki document is opened. For example, you could put your {{{<script src="..."></script>}}} syntax into a tiddler called LoadScripts, and then add {{{<<tiddler LoadScripts>>}}} in your MainMenu tiddler.
Since the MainMenu is always rendered immediately upon opening your document, the library will always be loaded before any other tiddlers that rely upon the functions it defines. Loading an external javascript library does not produce any direct output in the tiddler, so these definitions should have no impact on the appearance of your MainMenu.
''Creating dynamic tiddler content''
An important difference between this implementation of embedded scripting and conventional embedded javascript techniques for web pages is the method used to produce output that is dynamically inserted into the document:
* In a typical web document, you use the document.write() function to output text sequences (often containing HTML tags) that are then rendered when the entire document is first loaded into the browser window.
* However, in a ~TiddlyWiki document, tiddlers (and other DOM elements) are created, deleted, and rendered "on-the-fly", so writing directly to the global 'document' object does not produce the results you want (i.e., replacing the embedded script within the tiddler content), and completely replaces the entire ~TiddlyWiki document in your browser window.
* To allow these scripts to work unmodified, the plugin automatically converts all occurences of document.write() so that the output is inserted into the tiddler content instead of replacing the entire ~TiddlyWiki document.
If your script does not use document.write() to create dynamically embedded content within a tiddler, your javascript can, as an alternative, explicitly return a text value that the plugin can then pass through the wikify() rendering engine to insert into the tiddler display. For example, using {{{return "thistext"}}} will produce the same output as {{{document.write("thistext")}}}.
//Note: your script code is automatically 'wrapped' inside a function, {{{_out()}}}, so that any return value you provide can be correctly handled by the plugin and inserted into the tiddler. To avoid unpredictable results (and possibly fatal execution errors), this function should never be redefined or called from ''within'' your script code.//
''Accessing the ~TiddlyWiki DOM''
The plugin provides one pre-defined variable, 'place', that is passed in to your javascript code so that it can have direct access to the containing DOM element into which the tiddler output is currently being rendered.
Access to this DOM element allows you to create scripts that can:
* vary their actions based upon the specific location in which they are embedded
* access 'tiddler-relative' information (use findContainingTiddler(place))
* perform direct DOM manipulations (when returning wikified text is not enough)

!!!!!Examples
<<<
an "alert" message box:
><script show>
alert('InlineJavascriptPlugin: this is a demonstration message');
</script>
dynamic output:
><script show>
return (new Date()).toString();
</script>
wikified dynamic output:
><script show>
return "link to current user: [["+config.options.txtUserName+"]]";
</script>
dynamic output using 'place' to get size information for current tiddler:
><script show>
if (!window.story) window.story=window;
var title=story.findContainingTiddler(place).id.substr(7);
return title+" is using "+store.getTiddlerText(title).length+" bytes";
</script>
creating an 'onclick' button/link that runs a script:
><script label="click here" show>
if (!window.story) window.story=window;
alert("Hello World!\nlinktext='"+place.firstChild.data+"'\ntiddler='"+story.findContainingTiddler(place).id.substr(7)+"'");

<<<
!!!!!Installation
<<<
import (or copy/paste) the following tiddlers into your document:
''InlineJavascriptPlugin'' (tagged with <<tag systemConfig>>)
<<<
!!!!!Revision History
<<<
''2006.10.16 [1.5.2]'' add newline before closing '}' in 'function out_' wrapper. Fixes error caused when last line of script is a comment.
''2006.06.01 [1.5.1]'' when calling wikify() on script return value, pass hightlightRegExp and tiddler params so macros that rely on these values can render properly
''2006.04.19 [1.5.0]'' added 'show' parameter to force display of javascript source code in tiddler output
''2006.01.05 [1.4.0]'' added support 'onclick' scripts. When label="..." param is present, a button/link is created using the indicated label text, and the script is only executed when the button/link is clicked. 'place' value is set to match the clicked button/link element.
''2005.12.13 [1.3.1]'' when catching eval error in IE, e.description contains the error text, instead of e.toString(). Fixed error reporting so IE shows the correct response text. Based on a suggestion by UdoBorkowski
''2005.11.09 [1.3.0]'' for 'inline' scripts (i.e., not scripts loaded with src="..."), automatically replace calls to 'document.write()' with 'place.innerHTML+=' so script output is directed into tiddler content. Based on a suggestion by BradleyMeck
''2005.11.08 [1.2.0]'' handle loading of javascript from an external URL via src="..." syntax
''2005.11.08 [1.1.0]'' pass 'place' param into scripts to provide direct DOM access
''2005.11.08 [1.0.0]'' initial release

!!Usage
If you enter {ts} in your tiddler content (without the spaces) it will be replaced with a timestamp when you save the tiddler. Full list of formats:
* {ts} or {t} -> timestamp
* {ds} or {d} -> datestamp
* !ts or !t at start of line -> !!timestamp
* !ds or !d at start of line -> !!datestamp
(I added the extra ! since that's how I like it. Remove it from translations below if required)
!!Notes
* Change the timeFormat and dateFormat below to suit your preference.
* See also http://mptw2.tiddlyspot.com/#AutoCorrectPlugin
* You could invent other translations and add them to the translations array below.

En un mundo globalizado, en el que con frecuencia se toman decisiones de diseño de procesos y
de planificación, involucrando millones de pequeñas decisiones, muchas empresas de alto nivel
recurren a métodos lógico-matemáticos para ayudarse en las decisiones.
Con sus operaciones y decisiones, la empresa o institución tiene siempre uno o más objetivos (a
veces contradictorios en sus implicaciones), como por ejemplo:
*Minimizar costos
*Minimizar retrasos en las fechas de cumplimiento
*Minimizar riesgos
*Maximizar ganancias
*Maximizar calidad
*Minimizar desechos
Las miles de decisiones que deben tomarse en sistemas organizacionales complejos, con
frecuencia deben respetar ciertas limitaciones que invalidarían algunas posibles formas de
resolver los problemas, tanto por infactibilidad física, como porque implicarían el incumplimiento
de políticas y legislaciones.
Ejemplos de estas limitantes, que son llamadas “restricciones”, pueden ser:
*No agotar el presupuesto
*No puede utilizarse una máquina para procesar más de un producto a la vez
*No se puede exceder el horario laboral
*Lo que se produce, se debe almacenar o vender
*Para producir un bien, se requiere cierta cantidad de cierto material
*No puede utilizarse más material del que se dispone
*No puede generarse más contaminación de la que permite la legislación
*No puede dejar de satisfacerse la demanda
En el área de la Optimización, que forma parte de la ciencia de la Investigación de Operaciones, se
crean modelos matemáticos de las infinitas maneras “válidas” de resolver el problema o conjunto
de decisiones a tomar, y se genera una expresión matemática que permite saber una medida
cuantitativa del cumplimiento de un objetivo. De esta forma, el optimizador, junto a un equipo
interdisciplinario:
#Convierte el problema en un modelo matemático.
#Selecciona un método computacional para encontrar la solución que, respetando las
limitaciones, cumpla lo mejor posible el objetivo.
#Emplea el método para obtener una solución.
#Interpreta la solución para dar recomendaciones sobre el sistema real.
A lo largo del curso, se aprenderá a realizar estos 4 pasos, en particular para problemas
organizacionales. Esto se aclara, debido a que la optimización también se utiliza para una
innumerable cantidad de áreas, como:
#Diseño en ingeniería
#Ecología
#Diseño de sistemas de información
#Diseño de sistemas de control
#Análisis de datos
#Inteligencia Artificial
#Operaciones militares
Al final del curso, el estudiante podrá, en problemas típicos de decisiones organizacionales,
plantear modelos de optimización, introducirlos en paquetes computacionales especializados,
obtener resultados óptimos e interpretar sus respuestas.

!!!!!Configuration
<<<
<<option chkFloatingSlidersAnimate>> allow floating sliders to animate when opening/closing
>Note: This setting can cause 'clipping' problems in some versions of InternetExplorer.
>In addition, for floating slider animation to occur you must also allow animation in general (see [[AdvancedOptions]]).

!!!!!Revisions
<<<
2008.11.15 - 2.4.9 in adjustNestedSlider(), don't make adjustments if panel is marked as 'undocked' (CSS class). In onClickNestedSlider(), SHIFT-CLICK docks panel (see [[MoveablePanelPlugin]])
|please see [[NestedSlidersPluginInfo]] for additional revision details|
2005.11.03 - 1.0.0 initial public release. Thanks to RodneyGomes, GeoffSlocock, and PaulPetterson for suggestions and experiments.

===
//}}}
* ''"""+++""" (or """++++""") and """==="""''<br>marks the start and end of the slider definition, respectively. When the extra {{{+}}} is used, the slider will be open when initially displayed.
* ''"""(cookiename)"""''<br>saves the slider opened/closed state, and restores this state whenever the slider is re-rendered.
* ''"""! through !!!!!"""''<br>displays the slider label using a formatted headline (Hn) style instead of a button/link style
* ''"""^width^ (or just ^)"""''<br>makes the slider 'float' on top of other content rather than shifting that content downward. 'width' must be a valid CSS value (e.g., "30em", "180px", "50%", etc.). If omitted, the default width is "auto" (i.e., fit to content)
* ''"""*"""''<br>denotes "transient display": when a click occurs elsewhere in the document, the slider/floating panel will be automatically closed. This is useful for creating 'pulldown menus' that automatically go away after they are used. //Note: using SHIFT-click on a slider label will open/close that slider without triggering the automatic closing of any transient slider panels that are currently displayed, permitting ''temporary'' display of several transient panels at once.//
* ''"""@"""''<br>denotes "open on hover": the slider/floating panel will be automatically opened as soon as the mouse moves over the slider label, without requiring a click.
* ''"""{{class{[label=key|tooltip][altlabel|alttooltip]}}}"""''<br>uses label/tooltip/accesskey. """{{class{...}}}""", """=key""", """|tooltip""" and """[altlabel|alttooltip]""" are optional. 'class' is any valid CSS class name, used to style the slider label text. 'key' must be a ''single letter only''. altlabel/alttooltip specify alternative label/tooltip for use when slider/floating panel is displayed. //Note: you can use HTML syntax within the label text to include HTML entities (e.g., {{{»}}} (») or {{{►}}} (►), or even embedded images (e.g., {{{<img src="images/eric3.gif">}}}).//
* ''"""#panelID:"""''<br>defines a unique DOM element ID that is assigned to the panel element used to display the slider content. This ID can then be used later to reposition the panel using the {{{<<DOM move id>>}}} macro (see [[DOMTweaksPlugin]]), or to access/modify the panel element through use of {{{document.getElementById(...)}}}) javascript code in a plugin or inline script.
* ''""">"""''<br>automatically adds blockquote formatting to slider content
* ''"""..."""''<br>defers rendering of closed sliders until the first time they are opened.
Notes:
*You can 'nest' sliders as deep as you like (see complex nesting example below), so that expandable 'tree-like' hierarchical displays can be created.
*Deferred rendering (...) can be used to offset processing overhead until actually needed. However, this may produce unexpected results in some cases. Use with care.
* To make slider definitions easier to read and recognize when editing a tiddler, newlines immediately following the 'start slider' or preceding the 'end slider' sequences are automatically supressed so that excess whitespace is eliminated from the output.

!!!!!Revisions
<<<
2008.11.15 2.4.9 in adjustNestedSlider(), don't make adjustments if panel is marked as 'undocked' (CSS class). In onClickNestedSlider(), SHIFT-CLICK docks panel (see [[MoveablePanelPlugin]])
2008.11.13 2.4.8 in document.onclick(), if transient panel is not a sliderPanel or floatingPanel, hide it via CSS
2008.10.05 2.4.7 in onClickNestedSlider(), added try/catch around focus() call to prevent IE error if input field being focused on is currently not visible.
2008.09.07 2.4.6 added removeCookie() function for compatibility with [[CookieManagerPlugin]]
2008.06.07 2.4.5 in 'onmouseover' handler for 'open on hover' slider buttons, use call() method when invoking document.onclick function (avoids error in IE)
2008.06.07 2.4.4 changed default for chkFloatingSlidersAnimate to FALSE to avoid clipping problem on some browsers (IE). Updated Morpher hijack (again) to adjust regular sliderPanel styles as well as floatingPanel styles.
2008.05.07 2.4.3 updated Morpher hijack to adjust floatingPanel styles after animation without affecting other animated elements (i.e. popups). Also, updated adjustSliderPos() to account for scrollwidth and use core findWindowWidth().
2008.04.02 2.4.2 in onClickNestedSlider, handle clicks on elements contained //within// slider buttons (e.g., when using HTML to display an image as a slider button).
2008.04.01 2.4.1 open on hover also triggers document.onclick to close other transient sliders
2008.04.01 2.4.0 re-introduced 'open on hover' feature using "@" symbol
2008.03.26 2.3.5 in document.onclick(), if click is in popup, don't dismiss transient panel (if any)
2008.01.08 [*.*.*] plugin size reduction: documentation moved to ...Info tiddler
2007.12.28 2.3.4 added hijack for Animator.prototype.startAnimating(). Previously, the plugin code simply set the overflow to "visible" after animation. This code tweak corrects handling of elements that were styled with overflow=hidden/auto/scroll before animation by saving the overflow style and then restoring it after animation has completed.
2007.12.17 2.3.3 use hasClass() instead of direct comparison to test for "floatingPanel" class. Allows floating panels to have additional classes assigned to them (i.e., by AnimationEffectsPlugin).
2007.11.14 2.3.2 in onClickNestedSlider(), prevent SHIFT-click events from opening a new, empty browser window by setting "cancelBubble=true" and calling "stopPropagation()". Note: SHIFT-click is still processed as a normal click (i.e., it toggles the slider panel display). Also, using SHIFT-click will prevent 'transient' sliders from being automatically closed when another slider is opened, allowing you to *temporarily* display several transient sliders at once.
2007.07.26 2.3.1 in document.onclick(), propagate return value from hijacked core click handler to consume OR bubble up click as needed. Fixes "IE click disease", whereby nearly every mouse click causes a page transition.
2007.07.20 2.3.0 added syntax for setting panel ID (#panelID:). This allows individual slider panels to be repositioned within tiddler content simply by giving them a unique ID and then moving them to the desired location using the {{{<<DOM move id>>}}} macro.
2007.07.19 2.2.0 added syntax for alttext and alttip (button label and tooltip to be displayed when panel is open)
2007.07.14 2.1.2 corrected use of 'transient' attribute in IE to prevent (non-recursive) infinite loop
2007.07.12 2.1.0 replaced use of "*" for 'open/close on rollover' (which didn't work too well). "*" now indicates 'transient' panels that are automatically closed if a click occurs somewhere else in the document. This permits use of nested sliders to create nested "pulldown menus" that automatically disappear after interaction with them has been completed. Also, in onClickNestedSlider(), use "theTarget.sliderCookie", instead of "this.sliderCookie" to correct cookie state tracking when automatically dismissing transient panels.
2007.06.10 2.0.5 add check to ensure that window.adjustSliderPanel() is defined before calling it (prevents error on shutdown when mouse event handlers are still defined)
2007.05.31 2.0.4 add handling to invoke adjustSliderPanel() for onmouseover events on slider button and panel. This allows the panel position to be re-synced when the button position shifts due to changes in unrelated content above it on the page. (thanks to Harsha for bug report)
2007.03.30 2.0.3 added chkFloatingSlidersAnimate (default to FALSE), so that slider animation can be disabled independent of the overall document animation setting (avoids strange rendering and focus problems in floating panels)
2007.03.01 2.0.2 for TW2.2+, hijack Morpher.prototype.stop so that "overflow:hidden" can be reset to "overflow:visible" after animation ends
2007.03.01 2.0.1 in hijack for Slider.prototype.stop, use apply() to pass params to core function
2006.07.28 2.0.0 added custom class syntax around label/tip/key syntax: {{{{{classname{[label=key|tip]}}}}}}
2006.07.25 1.9.3 when parsing slider, save default open/closed state in button element, then in onClickNestedSlider(), if slider state matches saved default, instead of saving cookie, delete it. Significantly reduces the 'cookie overhead' when default slider states are used.
2006.06.29 1.9.2 in onClickNestedSlider(), when setting focus to first control, skip over type="hidden"
2006.06.22 1.9.1 added panel.defaultPanelWidth to save requested panel width, even after resizing has changed the style value
2006.05.11 1.9.0 added optional '^width^' syntax for floating sliders and '=key' syntax for setting an access key on a slider label
2006.05.09 1.8.0 in onClickNestedSlider(), when showing panel, set focus to first child input/textarea/select element
2006.04.24 1.7.8 in adjustSliderPos(), if floating panel is contained inside another floating panel, subtract offset of containing panel to find correct position
2006.02.16 1.7.7 corrected deferred rendering to account for use-case where show/hide state is tracked in a cookie
2006.02.15 1.7.6 in adjustSliderPos(), ensure that floating panel is positioned completely within the browser window (i.e., does not go beyond the right edge of the browser window)
2006.02.04 1.7.5 add 'var' to unintended global variable declarations to avoid FireFox 1.5.0.1 crash bug when assigning to globals
2006.01.18 1.7.4 only define adjustSliderPos() function if it has not already been provided by another plugin. This lets other plugins 'hijack' the function even when they are loaded first.
2006.01.16 1.7.3 added adjustSliderPos(place,btn,panel,panelClass) function to permit specialized logic for placement of floating panels. While it provides improved placement for many uses of floating panels, it exhibits a relative offset positioning error when used within *nested* floating panels. Short-term workaround is to only adjust the position for 'top-level' floaters.
2006.01.16 1.7.2 added button property to slider panel elements so that slider panel can tell which button it belongs to. Also, re-activated and corrected animation handling so that nested sliders aren't clipped by hijacking Slider.prototype.stop so that "overflow:hidden" can be reset to "overflow:visible" after animation ends
2006.01.14 1.7.1 added optional "^" syntax for floating panels. Defines new CSS class, ".floatingPanel", as an alternative for standard in-line ".sliderPanel" styles.
2006.01.14 1.7.0 added optional "*" syntax for rollover handling to show/hide slider without requiring a click (Based on a suggestion by tw4efl)
2006.01.03 1.6.2 When using optional "!" heading style, instead of creating a clickable "Hn" element, create an "A" element inside the "Hn" element. (allows click-through in SlideShowPlugin, which captures nearly all click events, except for hyperlinks)
2005.12.15 1.6.1 added optional "..." syntax to invoke deferred ('lazy') rendering for initially hidden sliders
removed checkbox option for 'global' application of lazy sliders
2005.11.25 1.6.0 added optional handling for 'lazy sliders' (deferred rendering for initially hidden sliders)
2005.11.21 1.5.1 revised regular expressions: if present, a single newline //preceding// and/or //following// a slider definition will be suppressed so start/end syntax can be place on separate lines in the tiddler 'source' for improved readability. Similarly, any whitespace (newlines, tabs, spaces, etc.) trailing the 'start slider' syntax or preceding the 'end slider' syntax is also suppressed.
2005.11.20 1.5.0 added (cookiename) syntax for optional tracking and restoring of slider open/close state
2005.11.11 1.4.0 added !!!!! syntax to render slider label as a header (Hn) style instead of a button/link style
2005.11.07 1.3.0 removed alternative syntax {{{(((}}} and {{{)))}}} (so they can be used by other formatting extensions) and simplified/improved regular expressions to trim multiple excess newlines
2005.11.05 1.2.1 changed name to NestedSlidersPlugin
2005.11.04 1.2.0 added alternative character-mode syntax {{{(((}}} and {{{)))}}}
tweaked "eat newlines" logic for line-mode {{{+++}}} and {{{===}}} syntax
2005.11.03 1.1.1 fixed toggling of default tooltips ("more..." and "less...") when a non-default button label is used. code cleanup, added documentation
2005.11.03 1.1.0 changed delimiter syntax from {{{(((}}} and {{{)))}}} to {{{+++}}} and {{{===}}}. changed name to EasySlidersPlugin
2005.11.03 1.0.0 initial public release

!Notes
* Borrows largely from ThemeSwitcherPlugin by Martin Budden http://www.martinswiki.com/#ThemeSwitcherPlugin
* Theme is cookie based. But set a default by setting config.options.txtTheme in MptwConfigPlugin (for example)
* Palette is not cookie based. It actually overwrites your ColorPalette tiddler when you select a palette, so beware.
!Usage
* {{{<<selectTheme>>}}} makes a dropdown selector
* {{{<<selectPalette>>}}} makes a dropdown selector
* {{{<<applyTheme>>}}} applies the current tiddler as a theme
* {{{<<applyPalette>>}}} applies the current tiddler as a palette
* {{{<<applyTheme TiddlerName>>}}} applies TiddlerName as a theme
* {{{<<applyPalette TiddlerName>>}}} applies TiddlerName as a palette

!Description
This plugin turns any number of tiddlers into a slide show. A single macro provides a flexible way to present a set of tiddlers, including:
#a full screen presentation that hides the TiddlyWiki structure (header, sidebar, main menu);
#a way to navigate through a set of tiddlers keeping the TiddlyWiki structure (similar to the [[NavigationMacro|http://tw.lewcid.org/#NavigationMacro]] by Saq Imtiaz);
#a display of all the selected tiddlers ready to be printed.
!Main features
Most features that are usually found in presentation software are available.
*Build a slide show from a list of tiddlers' titles or selecting a specific tag with optional sort
*Build a slide show from a single tiddler where slides are divided by a separator
*Fully customizable presentations (CSS knowledge required)
*Auto-advancing slide show (kiosk mode) and looping (circular mode)
*Incremental display (several overlays or layers in a slide)
*Optional clock with 4 different modes:
**local time
**elapsed time of presentation
**elapsed time for each slide
**countdown clock for a given period
*Screen blanking for pauses
!Installation
To install this plugin copy the tiddler SlideShowPlugin to your TiddlyWiki, label it with the ''systemConfig'' tag, save the TW and refresh the browser.
Optionally, you can also copy this documentation tiddler. If you don't, a link to the original one in my site is provided.
!Quick start
The simplest way to make a slide show is to create a new tiddler with references to all the tiddlers you want to include in your presentation. Any reference or group of references to tiddlers that should be skipped must be wrapped in a {{{exclude}}} class as in the following example:
{{{
MissingSlide
[[First slide|SlideShowExample-1]] {{exclude{(the tiddler SlideShowPluginDoc will not be included in the presentation)}}}
SlideShowExample-2
SlideShowExample-3
SlideShowExample-4
}}}
Add {{{<<slideShow>>}}} anywhere in the tiddler, close the edit form, click the ''slide show'' button and there you are. Move forward/backward in the presentation with the mouse left/right button. If you move the mouse pointer over the bottom of the browser window you will see a few navigation buttons. Click the ''x'' button or press the ''Escape'' key to exit.
!Options
{{{
<<slideShow
noClicks
noKeyboard
noOverlays
cycle
showAll
single
tiddler:tiddler
label:string
tooltip:string
tag:tag
sort:field
theme:tiddler

header:string
footer:string
>>
}}}
''noClicks''
Disables navigation through mouse clicks on the tiddlers. This is useful when there are lots of clickable elements in the presentation.
If you want to keep using the mouse to move around the presentation and there are occasional elements that require mouse clicking, these can be formatted with a {{{noClicks}}} class (read more [[here|http://www.tiddlywiki.com/#CustomCssClass]]).
''noKeyboard''
Disables keyboard navigation.
''noOverlays''
Disables the incremental display of overlays.
''cycle''
The slide shows runs in a continuous loop.
''showAll''
To print a presentation all the selected tiddlers are opened in the specified order. Press any key to return to the default TiddlyWiki layout.
''single''
Use this if a presentation is defined in a single tiddler.
''tiddler''
Use this option to indicate the tiddler where your slide show is defined when it is not the same one that contains the button that starts the presentation.
''label''
Text to replace the default text in the slide show button.
''tooltip''
Text to be shown when the mouse is over the slide show button.
''tag''
Use this option to create a slide show with the tiddlers with the provided tag instead of providing a list of tiddlers.
''sort''
If the ''tag'' option is used you can use this other option to sort the tiddlers according to a specific field. Valid values are: //created// (default), //modified//, //title// and //text//.
''theme''
A user provided tiddler containing CSS rules that define the style of the slide show. To redefine the default style, edit the SlideShowStyleSheet shadow tiddler.
''toc''
Choose the type of table of contents. Possible values: ''titles'' will enable the use of the tiddlers titles, ''headers'' (default) to choose html headers (h1, h2,...), anything else will disable the table of contents.
''auto''
The slide show auto advances after the defined number of seconds. The slide show can be paused by pressing the ''space bar''.
''clock''
Displays a clock near the navigation buttons at the bottom of the screen. Four types of clocks can be defined:
#''clock:0'' -- shows the local time.
#''clock:'+''' -- displays the elapsed time of the presentation. Click the clock display to reset the time.
#''clock:'-''' -- displays the elapsed for each slide. Click the clock display to reset the time.
#''clock:-20'' -- displays a countdown clock for the given (negative) number of minutes. Click the clock display to reset the time.
''clockFormat''
A string that defines the clock format. The default is '0hh:0mm:0ss' where the prefix '0' forces a leading zero.
''header''
A string to be used as a permanent header for the slide show. By default it's used the title of tiddler that defines the slide show.
''footer''
A string to be used as a permanent footer for the slide show. By default the footer is empty.
!Incremental display
A succession of overlays (or layers) can be defined in each slide by marking blocks of text with
{{{
{{overlay1{...some text...}}}, {{overlay2{...some text...}}}, {{overlay3{...some text...}}}, ...
}}}
The default name of the classes (//overlay//) can be redefined with //config.macros.slideShow.text.overlay = "layer"//, for example.
To costumize the way overlays are shown you can redefine the following CSS classes
*.previousOverlay
*.currentOverlay
*.nextOverlay
in a ~StyleSheet. The default style simply hides the next overlays and shows the current and the previous ones as normal text.
!Slide show navigation
You can navigate through a slide show using the keyboard or the mouse.
!!Mouse navigation
Left (right) clicking on a slide jumps to the next (previous) slide or overlay. To move to the first or last slides you must use the navigation bar at the bottom of the browser's window.
!!Keyboard
The following keys are defined:
*Home - first slide
*~PageUp - previous slide
*~PageDown - next slide
*End - last slide
*Escape - exit slide show
*Up arrow - first overlay
*Left arrow - previous overlay/slide
*Pause/Right arrow - next overlay/slide
*Down arrow - last overlay
*Spacebar - pause/resume slide show in auto advance mode, next overlay/slide otherwise
*B - blank screen and block the slide show
!Miscellaneous
Any block of text marked as
{{{
{{comment{For my eyes only!}}}
}}}
will not be displayed in the slide show.
All translatable strings are defined in //config.macros.slideShow.text// parameter. See SlideShowPluginMsgPT with the portuguese translation as an example.

|Name:|ToggleTagPlugin|
|Description:|Makes a checkbox which toggles a tag in a tiddler|
|Version:|3.1.0a|
|Date:|27-Jun-2011|
|Source:|http://mptw.tiddlyspot.com/#ToggleTagPlugin|
|Author:|Simon Baird <simon.baird@gmail.com>|
|License:|http://mptw.tiddlyspot.com/#TheBSDLicense|
!!Usage
{{{<<toggleTag }}}//{{{TagName TiddlerName LabelText}}}//{{{>>}}}
* TagName - the tag to be toggled, default value "checked"
* TiddlerName - the tiddler to toggle the tag in, default value the current tiddler
* LabelText - the text (gets wikified) to put next to the check box, default value is '{{{[[TagName]]}}}' or '{{{[[TagName]] [[TiddlerName]]}}}'
(If a parameter is '.' then the default will be used)
* TouchMod flag - if non empty then touch the tiddlers mod date. Note, can set config.toggleTagAlwaysTouchModDate to always touch mod date
!!Examples
|Code|Description|Example|h
|{{{<<toggleTag>>}}}|Toggles the default tag (checked) in this tiddler|<<toggleTag>>|
|{{{<<toggleTag TagName>>}}}|Toggles the TagName tag in this tiddler|<<toggleTag TagName>>|
|{{{<<toggleTag TagName TiddlerName>>}}}|Toggles the TagName tag in the TiddlerName tiddler|<<toggleTag TagName TiddlerName>>|
|{{{<<toggleTag TagName TiddlerName 'click me'>>}}}|Same but with custom label|<<toggleTag TagName TiddlerName 'click me'>>|
|{{{<<toggleTag . . 'click me'>>}}}|dot means use default value|<<toggleTag . . 'click me'>>|
!!Notes
* If TiddlerName doesn't exist it will be silently created
* Set label to '-' to specify no label
* See also http://mgtd-alpha.tiddlyspot.com/#ToggleTag2
!!Known issues
* Doesn't smoothly handle the case where you toggle a tag in a tiddler that is current open for editing
* Should convert to use named params

Aprenderemos sobre dos métodos (PERT y CPM) que sirven para la planificación y control de proyectos.
Son proyectos que equivalen a un problema de redes, porque implican el cálculo de la "ruta más larga".
Veremos cómo calcular el mínimo tiempo en que puede completar un proyecto (probabilística y determinísticamente), sin utilizar algoritmos clásicos de optimización.
