To get started with this blank TiddlyWiki, you'll need to modify the following tiddlers:
* SiteTitle & SiteSubtitle: The title and subtitle of the site, as shown above (after saving, they will also appear in the browser title bar)
* MainMenu: The menu (usually on the left)
* DefaultTiddlers: Contains the names of the tiddlers that you want to appear when the TiddlyWiki is opened
You'll also need to enter your username for signing your edits: <<option txtUserName>>
These InterfaceOptions for customising TiddlyWiki are saved in your browser

Your username for signing your edits. Write it as a WikiWord (eg JoeBloggs)

<<option txtUserName>>
<<option chkSaveBackups>> SaveBackups
<<option chkAutoSave>> AutoSave
<<option chkRegExpSearch>> RegExpSearch
<<option chkCaseSensitiveSearch>> CaseSensitiveSearch
<<option chkAnimate>> EnableAnimations

----
Also see AdvancedOptions
<<importTiddlers>>
If you check this box in the InterfaceOptions, TiddlyWiki will automatically SaveChanges every time you edit a tiddler. In that way there's a lot less chance of you losing any information. 

However, if you also have the SaveBackups checkbox ticked, you'll end up with a lot of archived files. You may prefer to select either one or the other.
Type of text clue in which rules are specified between entire categories rather than between items.  Categories need to be considered by their numerical values.  The category rules need to be parsed into one or more RestrictedValues.
*e.g. The number of pulleys is never the same as the number of levers
*e.g. The end weight is no less than 10 pounds fewer than the starting weight
CategoryRules can be of the NormalClue type but also of the SpecialClue type, meaning the rule needs to be re-examined later on during the solving process. The problem //~PocketPuzzle Logic Puzzles 1 Unhappy New Year (problem 16) has both:
*e.g. (implicit) none of the women sent a card to herself (NormalClue)
*e.g. (in the header) none of the women sent a card to the same person from which she received a card (SpecialClue)
The basic categories of clues for the software are as follows:
*NormalClue - directly leads to relationship(s) and requires no further reassessment
*SpecialClue - may directly lead to relationship(s) but needs further reassessment.  The majority of text clues provided in logic puzzles will be in this form simply because it is more challenging, and NormalClue don't constitute much of a puzzle.
Also follows a list of particularly interesting clues found in published logic puzzles.  They most often represent a challenge from a parsing/programming perspective and need to be considered during [[puzzled|http://puzzled.sf.net]]'s development.
*[[Gender]] - when text clues restrict possible values by considering the gender of first names
*Length of item - when the text clues restrict possible values based on the length of the item word itself
*NumericalElements - when the items in a category need to be considered numerically for comparison/computation purposes
*CategoryRules - when rules are specified between entire categories rather than between items.  Categories eligible for CategoryRules are ''often but not always'' considered by their numerical values (see NumericalElements)
*[[Enumeration]] - technique which consists in of listing all the item in a category using distinguishing attributes
[[Puzzled]]
It would be nice if the user had the option of viewing all entered text clues in a table and also have the ability to enable or disable certain clues to assess impact on the puzzle solving algorithms.
Graphically entered relationships need to be listed as well.
Type of text clue which enumerates a list of elements.  The ''elements'' in the enumeration are independent and cannot be associated together.
*e.g.The four mothers are: Lucie, the one who dresses in blue, the one who eats cake and the one whose baby weights 9 pounds.
*In the example, the following ''six'' VALUE_NO relationships need to be captured:
##Lucie does not wear blue
##Lucie does not eat cake
##Luce's baby does not weight 9 pounds
##The mother who dresses in blue does not eat cake
##The mother who dresses in blue does not have a 9-pound baby, and
##The mother who eats cake does not have a 9-pound baby.
*Mathematically, the number of VALUE_NO relationships is equal to the [[triangular number|http://en.wikipedia.org/wiki/Triangular_numbers]] of (items enumerated-1), so in the example: T~~(4-1)~~ = 3 + 2 + 1
*Also note the existence of relative enumerations when one of the enumerated item depends on another item.
**e.g. The four mothers were: Wendy, the one who married Phillip, the one named Mrs Courts and the one married two months before Mrs Courts
* Enumerations can be solved by building a list of possible items for each of the elements according to a chosen category (to be examined: does building a list of possible items for each of the enumerates according to more than one category help??)
* e.g. (//if listed according to the first name category//) the elements become:
** Wendy
** Either Jessica, Lucie or Brenda
** Either Lucie or Brenda
** Either Lucie or Brenda (thus Jessica married Philip)
A type of RestrictedValues determined when items in numerical-like categories are compared with one another. Extremes are computed easily from the HintsTable at the beginning of the puzzle solving process.  The offset values are important because 'offset' positions from each of the elements in the equation are 'taken out' such that:
##the lower element will see the 'offset'-highest values 'taken-out'
##the higher element will see the 'offset'-lowest values 'taken-out'
*e.g. A's baby is two (note that the offset is 2) pounds lighter than B's baby, where the weight items are 6,7,8,9,10 pounds, means that A's baby (the lower element) cannot be 9 or 10 pounds and that B's baby (the higher element) cannot be 6 or 7 pounds.
Using the gender of names in the clue text:
e.g. Fergus isn't the man who both ate the chicken pot pie and the lemon cheesecake
* leads to the elimination of Josie in favour of Timothy.
* work around: user defines a negative relationship between all female names and the listed foods
A table used to capture relationship between items that have a mathematical expression such as equal, less than, more than, n less than, n more than, unequal (where n is called [[offset]].  Once captured in the HintsTable, new relationships can be discovered using one of the three algebraic method discovered (see LogicElements).  A HintsTable looks like:
|!Serial|!Text Clue|!unknow_x|!category_x|!item_x|!unknow_y|!category_y|!item_y|![[offset]]|
| a. | 1. |levers|springs|5|pulleys|cheese|gorgonzola|0|
| b. | 2. |levers|pulleys|5|pulleys|cheese|limburger|0|
| c. | 3. |levers|cheese|tilsit|pulleys|springs|4|0|
| d. | 4. |levers|cheese|limburger|pulleys|levers|3|0|
| e. | 1. |springs|cheese|gorgonzola|springs|cheese|camembert|+1|
| f. | 2. |springs|pulleys|5|springs|cheese|wensleydale|+1|
| g. | 3. |springs|cheese|tilsit|springs|levers|4|+1|

* As a convention the offset is defined as what x has over y
* The HintsTable need not to be sorted by [[offset]] value but it makes the discovery of new algebraic relationships much easier

To import tiddlers from another ~TiddlyWiki file, or from an external website, follow these instructions.
#If the tiddler is on an external site, first copy the URL of the tiddler that you wish to import into your clipboard
#Open your ~TiddlyWiki file from your computer.
#Click on the 'Backstage' link that you can see at the very top right hand side of the page.
#In the expanded menu, click on 'Import'. You will then see a window that looks like this - and you can follow the guidance from there. Note that you may need to grant authorisation to your ~TiddlyWiki file to import tiddlers - this is fine and expected.
<<importTiddlers>>
//Note also that the popular [[Firebug|http://www.joehewitt.com/software/firebug/]] extension for Firefox interferes with ImportTiddlers if its "Show XMLHttpRequest" option is switched on//

|Description|Insert Javascript executable code directly into your tiddler content.|

''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.  You may also include a {{{title="..."}}} parameter to specify the 'tooltip' text that will appear whenever the mouse is moved over the onClick link text

''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>
	// uncomment this: 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" title="clicking this link will show an 'alert' box" show>
   if (!window.story) window.story=window;
   alert("Hello World!\nlinktext='"+place.firstChild.data+"'\ntiddler='"+story.findContainingTiddler(place).id.substr(7)+"'");
</script>
loading a script from a source url:
>http://www.TiddlyTools.com/demo.js contains:
>>{{{function demo() { alert('this output is from demo(), defined in demo.js') } }}}
>>{{{alert('InlineJavascriptPlugin: demo.js has been loaded'); }}}
><script src="demo.js" show>
	return "loading demo.js..."
</script>
><script label="click to execute demo() function" show>
	demo()

<<<
!!!!!Revision History
<<<
''2007.02.19 [1.6.0]'' added support for title="..." to specify mouseover tooltip when using an onclick (label="...") script
''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

This tiddler describes the various logic elements used by puzzled.
!Manual
*entered graphically by the user using the Graphical User Interface
!From Clue
* determined by the parser from the text entered
!Cross
* for VALUE_NO relationships only
* stems from the discovery/entering of a VALUE_YES relationship and is represented graphically by a cross
!Uniqueness
* stems from (numberItems-1) VALUE_NO relationships in a category, which automatically identify the left-out item as the VALUE_YES
!Transposed
* replicating known relationships on either side of a VALUE_YES to ensure graphical/geographical consistency
!Commonality
* used when the only possible values share a commonality.
* e.g. Paul lives in either the yellow or blue house, but both the yellow and blue house cannot be where the cat lives, therefore Paul does not have a cat.
* when searching for Commonality relationships, examine when there are 2 to numberItems-2 possible value.  If there were 1 possible value it would become a VALUE_YES, and if there were numberItems-1 possibilities that all share a common characteristic, then a VALUE_YES would be defined there: Paul lives in either the the white, yellow, blue and green house, neither of which can be where the cat lives, thus the cat lives in the red house, and Paul does not have a cat which is already discovered by a Cross followed by a Transposed search
![[Restricted values|RestrictedValues]]
* derived from [[special clues|SpecialClue]], values that are impossible for an element because two numerical elements are used in an algebraic-like equation which causes incompatible values
* includes [[delta]]s until sign is determined, then processed via the [[Hints Table|HintsTable]].
!Algebraic
* relationship derived mathematically using the HintsTable
* Three types of algebraic processes have been discovered: [[Type 1]], [[Type 2]] and [[Type 3]].
![[Enumeration]]
* relationship discovered following the elimination of options as part of an enumeration.

A normal clue is specific enough that further reassessments are not necessary, as it provides VALUE_NO or VALUE_YES relationships at the onset, and will not be provide additional information in the future.  It is distinct from a [[special clue|SpecialClue]].
*e.g. Martin lives in the green house. (VALUE_YES)
*e.g. Yohan does not drink tea. (VALUE_NO)
Items which are to be considered at face value such as weight/age/year/cost/rank, etc
e.g. a painting's production year is one of 2002,2003,2005,2006 and clue text reads:
Spring was completed three years earlier than the painting by Max Dawkins
* software needs to know if the value of the item is important for the deductions, or simply the position of the item in the category
* an option is to consider all numerical values as meaningful, but the user would need to know not to enter these items textually, which is counter intuitive for rankings such as first, second, third, fourth, fifth (would have to be entered 1,2,3,4,5)
* any numerical item is subject to a set of mathematical expressions such as +,- but also the less common *,/ :
 eg. the weight of John's parcel is twice as heavy as the weight of Lucie's parcel.
* pay special attention to problem 5 (Dress Design) of the Pocket Puzzles Logic Puzzle 1 booklet which uses positional information (could it be handled as a normal category with less than / greater than??)
* the months of the year and the days of the week need to be considered as numerical values as it leads to eliminations of values
Follows is a list of objects:
<<tagging Object>>
Type of SpecialClue in which a [[Relationship]] is known to be true for one of the two elements mentioned.  At the onset, it is not possible to derive a VALUE_YES relationship but it may be possible to derive one or more VALUE_NO relationship(s).

!Purpose
This tiddler captures the various logic elements required to solve some real-life puzzled found in puzzle magazines and booklets.  It will be instrumental to test drive puzzle's LogicElements as they are implemented.
Object responsible to search for new relationships using the [[logic elements|LogicElements]] that are implemented.
[[Puzzled|http://puzzled.sf.net]] is an open-source java application which will ultimately help you solve grid-type logic problems by understanding pseudo-english translation of the clues provided with the problem. 

This [[TiddlyWiki|http://www.tiddlywiki.com/]] is used by the [[Puzzled|http://puzzled.sf.net]] developer to keep notes about logic puzzles, the design decisions during the development phase of Puzzled, as well as generic notes about logic puzzles solved by the developer which present a challenge from a programming perspective.
Object which represents a VALUE_YES or VALUE_NO relationship between two items of different categories. The relationship also has a sequence number given by the [[Sequencer]] in order to implement RollBack.  A relationship can be visually represented on the puzzle grid by a tile depending of its value, and is listening to mouse events so the user can manually enter relationship values.
Restricted values are values that are impossible for a certain item in a certain category because of the text clues that have been provided.  It includes first and foremost the [[Extremes]] when items are compared quantitatively in numerical-like categories, but may also include other values depending of the relationship between items.
*The HintsTable is the primary tool to identify restricted values and must be reassessed frequently to 'take out' impossible values that have crept up by VALUE_NO or VALUE_YES relationships in the grid.
* It's like a special bond created between two value bubbles in the grid.  The hints table reassessment ensures the bond is respected when there are changes in either set (bubble) of elements.
*Additionally, some restricted values appear based on the oddities in the value sets:
** e.g. months be Apr Jun Jul Aug, the fact that May is missing could exclude potential values from an unknown if A is one month earlier than B, A can't be Apr and B can't be Jun. The extremes also prevent A from being Aug and B from being Apr.
** e.g. A's pulleys are equal to B's levers, pulley items being 1,3,4,5,6 and lever items being 1,2,3,4,5.  Neither can be 2 or 6.
*Mathematical equations such as less than, double, half also result in restricted values.
The software needs to have the ability to roll back if the user changes a manually entered relationship.
*In those instances, the relationships discovered following the initial user-entered relationship have to be removed completely, the initial user-entered relationship has to be modified, and the processor needs to re-discover relevant relationships.
*Relationships that are not manually entered, such as those derived from text clues or using any of the logic elements, cannot be modified by the user using the Graphical User Interface.
*In order to achieve roll-back, a [[Sequencer]] object needs to exist and its current value needs to be assigned to each relationship.

All about AboutMe here.
Object which simply assign an incrementing sequence number to the [[Relationship]] created.
The relationship sequence is required to implement the RollBack feature.
<<search>><<closeAll>><<permaview>><<newTiddler>><<slider chkSliderOptionsPanel OptionsPanel "options ยป" "Change TiddlyWiki advanced options">>
used induring the design and development of [[puzzled|http://puzzled.sf.net]]
Puzzled notes
Contrary to a [[normal clue|NormalClue]], a [[special clue|SpecialClue]] is a text clue that needs to be reassessed periodically because it does not, at the onset, provide sufficient information to determine VALUE_YES relationships.
*e.g. A's baby is two pounds lighter than B's baby. 
Note however that this type [[special clue|SpecialClue]] implies immediate VALUE_NO relationships consisting of [[extremes|Extremes]] and possibly further [[restricted values|RestrictedValues]] as the puzzle solving progresses.
*RollBack handling
*HintsTable implementation 
** Algebraic 1 & 2: only executed after hints are added to the table
**1. discovery from items in the same category
**2. deduction from one item appearing in either side of a same unknown_x
**3. algebra 3: dependent upon relationjavascript:;ship to discover other ones
*how to handle > < : as special clue only or in table (ref [[Type 2]])
*What is the need for VALUE_UNKNOWN?
*[[delta]]: SpecialClue until sign is determined and then into HintsTable, or dormant in the HintsTable as an unsigned [[offset]] used for RestrictedValues only?? (should a delta simply be considered as an [[Or]] rule?)
*[[Enumeration]] handling, [[Or]] handling

A relationship defined as the two related items are not connected.

*In puzzled, its value is arbitrarily defined in the puzzled.data.Constants interface as -1.
*Represented by the absence of an 'X' or an 'O'.
*In puzzled, its value is arbitrarily defined in the puzzled.data.Constants interface as -1.
The [[relationship|Relationship]] grid is initialized with all tiles worth VALUE_UNKNOWN at the onset, until their value is changed by a text clue or a deduced relationship. 
It is necessary to create all the [[relationships|Relationship]] even before VALUE_YES or VALUE_NO is known because the relationships are also tiles in the Graphical User Interface on which the user can click. (have an mouse click event listener).
Positive relationship between two items. 
*It is graphically represented by an 'O'.
*In puzzled, its value is arbitrarily defined in the puzzled.data.Constants interface as 1.
The numerical difference between two elements as written in the text rules.  It is the right-most column in a HintsTable and should be the sort key to ease algebraic type discoveries.
* In the HintsTable, the offset sign must be explicitly specified as unsigned offsets are offsets for which the direction in unknown.  Offsets of unknown sign are also called [[delta]] clues and cannot be used by the processor for algebraic discovneries until sign is know (only useful as RestrictedValues at the onset).
