%
%%%%%%%%%%%%%%% Release 3.9
%
% History:
%
% - October 04 2005 - revision 3.9 -
% * ADD: - \setalcaphskip command which set the horizontal skip before Algorithm: in caption when
% used in ruled algorithm.
% * ADD: - SetAlgoInsideSkip command which allows to add an extra vertical space before and after
% the core of the algorithm (ie: \SetAlgoInsideSkip{bigskip})
% * CHANGE: - caption, when used with figure option, is no more controlled by algorithm2e package
% and so follows the exact behaviour of figures. The drawback is that you cannot change
% the typo with AlTitleFnt or CapFnt. The avantage is that if you use caption package,
% it works.
% * FIX: - problem with numbering line and pdflatex
% * FIX: - error when algorithm2e package was used with beamer and listings together
% - February 12 2005 - revision 3.8 -
% * FIX: - extra line with noend option.
% - February 10 2005 - revision 3.7 -
% * ADD: - sidecomment: different macros allowing to put text right after code
% on the same line. They are defined in the same time comment macros
% are defined with a star after the macro name. By default comments
% are right justified but this can be change with appropriate option
% in the macro. Ex:
% . default: \tcc*{side comment}
% . same as previous: \tcc*[r]{side comment}
% . left justify: \tcc*[l]{side comment}
% . here: \tcc*[h]{side comment} don't put the end of line mark before
% comment (; by default) and don't end the line.
% . flushed: \tcc*[f]{side comment} same as the precedent but right
% justified
% * ADD: - scright OPTION (default): right justified side comments (side comments
% are flushed to the righr)
% * ADD: - scleft OPTION: left justified side comments (side comments are
% put right after the code line)
% * ADD: - \SetSideCommentLeft acts as scleft option
% * ADD: - \SetSideCommentRight acts as scright option
% * ADD: - block like macro side text: all macro defining a block allows now
% to put text right after key words by putting text into (). Done to
% be used with sidecomment macros, but all text can be used. Ex:
% \eIf(\tcc*[f]{then comment}){test}{then text}(else side text){else text}
% * ADD: - fillcomment OPTION (default): end mark of comment is flushed to the
% right so comments fill all the width of text
% * ADD: - nofillcomment OPTION: end mark of comment is put right after the
% comment
% * ADD: - \SetNoFillComment acts as nofillcomment option.
% * ADD: - \SetFillComment acts as fillcomment option.
% * ADD: - dotocloa OPTION which adds an entry in the toc for the list of
% algorithms. This option load package tocbibind if not already done
% and so list of figures and list of tables are also added in the toc.
% If you want to control which ones of the lists will be added in the
% toc, please load package tocbibind before package algorithm and give
% it the options you want.
% * FIX: - vertical spacing for uif macro with noend option
% * FIX: - all the compatibility problems between caption and other packages
% * FIX: - typographical differences between list of algorithms and other lists
% when in report or book
%
% - January 24 2005 - revision 3.6 -
% * FIX: - vertical spacing and space characters at the beginning or end of
% comments.
% line numbers of comments not in the nlsty.
% Thanks to Arnaud Giersch for his comments and suggestions.
% * FIX: - Set*Sty macro: the styles defined was not protected and was modified
% by surrounding context. For example KwTo in a \For{}{} was in bold AND
% italic instead of just in bold.
% * FIX: - line number misplacement after \Indp
%
% - January 21 2005 - revision 3.5 -
% * ADD: - hidden numbering of the lines. Lines are auto-numbered but numbers
% are shown only on lines you specify:
% * linesnumberedhidden option or \linesnumberedhidden macro activate
% this functionnality.
% * \showln and \showlnlabel{lab} macros make the number visible on
% the line. \showlnlabel{lab} allows to set a label for this line.
% Thanks to Samson de Jager who makes this suggestion and provides the
% macros.
% * ADD: - \AlCapFnt and \SetAlCapFnt which allow to have a different font for
% caption. Works like \AlFnt and \SetAlFnt and by default is the same.
% * ADD: - \AlCapSkip skip length. This vertical space is added before caption
% in plain ou boxed mode. It allows to change distance between text
% and caption.
% * FIX: - caption compatible with IEEEtran class.
% * FIX: - some vertical spacing error with \uIf macros (Thanks to Arnaud Giersch)
% * FIX: - Procedure and Function: lines are also numbered like algorithms
% * FIX: - CommentSty was not used for Comments
%
% - January 10 2005 - revision 3.4 -
% * FIX: - caption compatible with new release of Beamer class.
%
% - June 16 2004 - revision 3.3 -
% * FIX: - Hyperlink references of Hyperref package works now if compiled with pdflatex
% and [naturalnames] option of hyperref package is used.
% * FIX: - algorithm[H] had problem in an list environment - corrected
% * FIX: - interline was not so regular in nested blocks - corrected
% * ADD - \Setvlineskip macro which set the vertical skip after the little horizontal
% rule which closes a block in Vlined mode. By default 0.8ex
%
% - June 11 2004 - revision 3.2 - AUTO NUMBERING LINES !!!
% * ADD: auto numbering of the lines (the so asked and so long awaiting feature)
% this feature is managed by 3 options and 3 commands:
% - linesnumbered option: lines of the algo are numbered except for comments and
% input/output (KwInput and KwInOut)
% - commentsnumbered option: makes comments be numbered
% - inoutnumbered option: makes data input/output be numbered
% - \nllabel{lab} labels the line so you can cite with \ref{lab}
% - \linesnumbered make the following algorithms having auto-numbered lines
% - \linesnotnumbered make the following algorithms having no auto-numbered lines
% * Change: algo2e option renames listofalgorithm in listofalgorithme
% * FIX: new solution for compatibility with color package, more robust and not tricky.
% Many thanks to David Carlisle for his advices
%
% - June 09 2004 - revision 3.1 -
% * Change: \SetKwSwitch command defines an additionnal
% macro \uCase and \Case prints end
% * Change: now macros SetKw* do a renewcommand if the
% keyword is already defined. So you can redefine
% default definition at your own convenience or
% change your definition without introducing a
% new macro and changing your text.
% * ADD: new macro \SetKwIF which do \SetKwIf and
% \SetKwIfElseIf.The following default definition has been added:
% \SetKwIF{If}{ElseIf}{Else}{if}{then}{else if}{else}{endif}
% and so you get the macros;
% \If \eIf \lIf \uIf \ElseIf \uElseIf \lElseIf \Else
% \uElse \lElse
% * ADD: new macro \SetAlgoSkip which allow to fix the
% vertical skip before and after the algorithms.
% Default is smallskip, do \SetAlgoSkip{} if you
% don't want an extra space or \SetAlgoSkip{medskip}
% or \SetAlgoSkip{bigskip} if you want bigger space.
% * ADD: macro \SetKwIf defines in addition a new macro
% \uElse (depending on wat name you
% have given in #2 arg).
% * ADD: macro \SetKwIfElseIf defines in addition a new macro
% \uElse and \ugElseIf (depending on what name you
% have given in #2 and #3 arg).
% * Change: baseline of algorithm is now top, so two
% algorithms can be put side by side.
% * FIX: Compatibility with color package solved. The problem
% was due to a redefinition of standard macros by color package
% This solves compatibility problem with other packages
% as pstcol or colortbl.
% (notified by Dirk Fressmann, Antti Tarvainen and Koby Crammer)
% * Fix: extra little shift to the right with boxed style
% algorithm removed (notified by P. Tanovski)
% * Fix: algoln option was buggy (notified bye Jiaying Shen)
% * Fix: german and portuges option didn't work due to bad
% typo (notified by Martin Sievers, Thorsten Vitt
% and Jeronimo Pellegrini)
%
% - February 13 2004 - revision 3.0 -
% * Major revision which makes the package independent from
% float.sty, so now
% - algorithm* works better, in particular can be used in
% multicols environments
% - (known bug corrected)
% [H] works now for all sort of environment but is
% handled differently for classic environment and star
% environment (algorithm, figure, procedure and
% function). For star environment, H acts like for
% classical figure environment, so it doesn't stay here
% absolutely.
% - (known bug corrected)
% you can use now floatflt package with algorithm
% package and even with figure option. Beware that if
% you want to put an algorithm inside a floatingfigure,
% it cannot be floating, so [H] is required and then
% figure option should not be used, since standard
% figure[H] are still floating with LaTeX.
% * boxruled: a new style added. Possible now since no
% style no more defined by the float package.
% * nocaptionofalgo: dosen't print Algorithm #: in the
% caption for algorithm in ruled or algoruled style.
% note: this is just documentation of a macro which was
% already in the package.
% - December 14 2003 - revision 2.52 -
% * output message shorter
% * french keyword macro \PourTous was missing for
% longend option, it has been added.
% * TitleofAlgo prints Function or Procedure in
% corresponding environments.
%
% - October 27 2003 - revision 2.51 - Revision submitted to CTAN archive
% * correction of a minor which make caption in procedure
% and function to be blanck with pdfscreen package
% (thanks to Joel Gossens for the notification)
% * add two internal definition to avoid some errors when
% used with Hyperref package (Hyperref package need to
% define new counter macro from existing ones, and
% don't do it for algorithm2e package, so we do it)
%
% - October 17 2003 - revision 2.50 - first revision for CTAN archive
%
% * add \AlFnt and \SetAlFnt{font} macros:
% \AlFnt is used at the beginning of the caption and the
% body of algorithm in order to define the fonts used
% for typesetting algorithms. You can use it elsewhere
% you want to typeset text as algorithm. For example
% you can do \SetAlFnt{\small\sf} to have algorithms
% typeset in small sf font. Default is nothing so
% algorithm is typeset as the text of the document.
% * add \AlTitleFnt{text} and \SetAlTitleFnt{font} macros:
% The {Algorithm: } in the caption is typeset with
% \AlTitleFnt{Algorithm:}. You can use it to have text
% typeset as {Algorithm:} of captions. Default is
% textbf.
% Default can be redefined by \SetAlTitleFnt{font}.
% * add CommentSty typo for text comment.
% * add some compatibility with hyperref package (still
% an error on multiply defined refs but pdf correctly
% generated)
% * flush text to left in order to have correct
% indentation even with class as amsart which center
% all figures
% * add german, portugues and czech options for title of
% algorithms and typo.
% * add portuguese translation of predefined keywords
% * add czech translation of some predefined keywords
%
% - December 23 2002 - revision 2.40
% * add some french keyword missing
% * add function* and procedure* environment like
% algorithme* environment: print in one column even
% if twocolumn option is specified for the document.
% * add a new macro \SetKwComment to define macro which
% writes comments in the text. First argument is the
% name of the macro, second is the text put before the
% comment, third is the text put at the end of the
% comment.Default are \tcc and \tcp
% * add new options to change the way algo are numbered:
% [algopart] algo are numbered within part (counter must exist)
% [algochapter] algo are numbered within chapter
% [algosection] algo are numbered within section
%
% - March 27 2002 - revision 2.39
% * Gilles Geeraerts: added the \SetKwIfElseIf to manage
% if (c)
% i;
% else if (c)
% i;
% ...
% else
% i;
% end
% * Also added \gIf \gElsIf \gElse.
%
% - January 02 2001 - revision 2.38
% * bugs related to the caption in procedure and function
% environment are corrected.
% * bug related to option noend (extra vertical space added
% after block command as If or For) is corrected.
% * czech option language added (thanks to Libor Bus: [email protected]).
%
% - October 16 2000 - revision 2.37
% * option algo2e added: change the name of environment
% algorithm into algorithm2e. So allow to use the package
% with some journal style which already define an algorithm
% environment.
%
% - September 13 2000 - revision 2.36
% * option slide added: require package color
% * Hack for slide class in order to have correct
% margins
%
% - November 25 1999 - revision 2.35
% * revision number match RCS number
% * Thanks to David A. Bader, a new option is added:
% noend: no end keywords are printed.
%
% - November 19 1999 - revision 2.32
% * minor bug on longend option corrected.
%
% - August 26 1999 - revision 2.31
% * add an option : figure
% this option makes algorithms be figure and so are numbered
% as figures, have Figure as caption and are put in
% the \listoffigures
%
% - January 21 1999 - revision 2.3 beta
% add 2 new environments: procedure and function.
% These environments works like algorithm environment but:
% - the ruled (or algoruled) style is imperative.
% - the caption now writes Procedure name....
% - the syntax of the \caption command is restricted as
% follow: you MUST put a name followed by 2 braces like
% this ``()''. You can put arguments inside the braces and
% text after. If no argument is given, the braces will be
% removed in the title.
% - label now puts the name (the text before the braces in the
% caption) of the procedure or function as reference (not
% the number like a classic algorithm environment).
% There are also two new styles : ProcNameSty and
% ProcArgSty. These style are by default the same as FuncSty
% and ArgSty but are used in the caption of a procedure or a
% function.
%
% - November 28 1996 - revision 2.22
% add a new macro \SetKwInParam{arg1}{arg2}{arg3}:
% it defines a macro \arg1{name}{arg} which prints name in keyword
% style followed byt arg surrounded by arg2 and arg3. The main
% application is to a function working as \SetKwInput to be used
% in the head of the algorithm. For example
% \SetKwInParam{Func}{(}{)} allows
% \Func{functionname}{list of arguments} which prints:
% \KwSty{functioname(}list of arguments\KwSty{)}
%
%
% - November 27 1996 - revision 2.21 :
% minor bug in length of InOut boxes fixed.
% add algorithm* environment.
%
% - July 12 1996 - revision 2.2 : \SetArg and \SetKwArg macros removed.
%
% \SetArg has been removed since it never has been
% documented.
% \SetKwArg has been removed since \SetKw can now
% take an argument in order to be consistent with
% \SetKwData and \SetKwFunction macros.
%
% - July 04 1996 - revision 2.1 : still more LaTeX2e! Minor compatibility break
%
% Macros use now \newcommand instead of \def, use of \setlength,
% \newsavebox, ... and other LaTeX2e specific stuff.
% The compatibility break:
% - \SetData becomes \SetKwData to be more consistent. So the old
% \SetKwData becomes \SetKwInput
% - old macros \titleofalgo, \Freetitleofalgo and \freetitleofalgo
% from LaTeX209 version which did print a warning message and call
% \Titleofalgo in version 2.0 are now removed!
%
% - March 13 1996 - revision 2.0: first official major revision.

% - shortend, longend, noend : short or long end keyword as endif for e.g.
%
% defaults are; english,plain,resetcount,titlenotnumbered

%
% Short summary
% -------------
%
% algorithm is an environment for writing algorithm in LaTeX2e
% It provide macros that allow you to create differents
% sorts of key words, therefore a set of predefined key word
% is gived.
%
% IT should be used as follows
%
% \begin{algorithm}
% ...
% ...
% \end{algorithm}
%
%
% IMPORTANT : each line MUST end with \;
%
% Note that if you define macros outside algorithm environment they
% are avaible in all the document and particulary you can use then
% inside all algorithms without re-define them.
%
% an example:
%
% \begin{algorithm}[H]
% \SetLine
% \AlgData{this text}
% \AlgResult{how to write algorithm with \LaTeX2e }
%
% initialization\;
% \While{not at end of this document}{
% read current section\;
% \eIf{understand}{
% go to next section\;
% current section becomes this one\;
% }{
% go back to the beginning of current section\;
% }
% }
% \caption{How to write algorithm}
% \end{algorithm}
