[Tex/LaTex] Renaming Algorithm to Heuristic in algorithm2e package

algorithm2ealgorithmsnaming

I am trying to write some heuristics for a problem using the algorithm2e package.

However as you may know, when you write :

\begin{algorithm}
\caption{Heuristic 1: Name of Heuristic}
 ...
\end{algorithm}

The output says

Algorithm 1: Heuristic 1: Name of Heuristic

Do someone know how do I get it to write:

Heuristic 1: Name of Heuristic

instead ?

PS. I don't know if this command does the trick: \SetAlgoRefName{} I could not get it to work, anyone has an example where they used it?

Best Answer

\SetAlgorithmName requires three arguments:

\SetAlgorithmName{algorithmname}{algorithmautorefname}{list of algorithms name}

such as

\SetAlgorithmName{Heuristic}{heuristic}{List of Heuristics}

You could also directly redefine the macros of the algorithm2e package:

\renewcommand*{\listalgorithmcfname}{List of Heuristics}
\renewcommand*{\algorithmcfname}{Heuristic}
\renewcommand*{\algorithmautorefname}{heuristic}

Solution

Do not mix lst: with Algorithm floats. The previous solution used \newcommand{\algorithmname}{Listing}, but this could result in LaTeX Error: Command \algorithmname already defined. Instead, apply the following changes:

Rename lst: to alg:.

Change the preamble to:

\usepackage{float}
\floatname{algorithm}{Listing}
\renewcommand{\algorithmname}{Listing}

This does not change the "List of Algorithms" to "List of Listings". The text is found in "stdfloats.inc":

Float
    Type                  algorithm
    GuiName               Algorithm
    Placement             tbp
    Extension             loa
    NumberWithin          none
    Style                 ruled
    ListName              "List of Algorithms"
    LaTeXBuiltin          false
End

The improper way to fix this is:

Edit stdfloats.inc.
Change "List of Algorithms" to "List of Listings".
Click Tools >> Reconfigure.
Restart LyX.

At this point, "List of Algorithms" will read "List of Listings".

[Tex/LaTex] Change the algorithm enumeration in the algorithm2e package

With the algorithmic environment, you're probably using the algorithms bundle or possibly the algorithmicx package (both provide that environment). The algorithm environment's name is stored in \ALG@name that you can modify using \renewcommand.

Here's a way to modify the default Algorithm to your liking:

enter image description here

\documentclass{article}
\usepackage{algorithm}% http://ctan.org/pkg/algorithms
\usepackage{algpseudocode}% http://ctan.org/pkg/algorithmicx
\makeatletter
\renewcommand{\ALG@name}{Algoritme}% Afrikaans
\makeatother
\begin{document}
\begin{algorithm}
  \caption{Hierdie is 'n algoritme.}
  \begin{algorithmic}[1]
    \State Iets
    \State Iets anders
  \end{algorithmic}
\end{algorithm}
\end{document}

Note that this is actually independent of the algorithmic environment.

The algorithm2e package is a more complete package in the sense that it provides its own algorithm environment. It also supports a number of language options by default, including english, french, czech, german, portuguese, italiano, and slovak. For example, using (from the algorithm2e documentation):

\documentclass{article}
\usepackage[portuguese]{algorithm2e}% http://ctan.org/pkg/algorithm2e
\begin{document}
\begin{algorithm}[H]
  \SetAlgoLined
  \KwData{this text}
  \KwResult{how to write algorithm with \LaTeX2e }
  initialization\;
  \While{not at end of this document}{
    read current\;
    \eIf{understand}{
      go to next section\;
      current section becomes this one\;
    }{
      go back to the beginning of current section\;
    }
  }
  \caption{How to write algorithms}
\end{algorithm}
\end{document}

produces

enter image description here

These language options set a number of commands other than just the algorithm name (stored in \algorithmcfname). Here's an extract for the portuguese language option:

\DeclareOption{portuguese}{%
\renewcommand{\listalgorithmcfname}{Lista de Algoritmos}%
\renewcommand{\algorithmcfname}{Algoritmo}%
\renewcommand{\algorithmautorefname}{algoritmo}%
\renewcommand{\algorithmcflinename}{linha}%
\renewcommand{\algocf@typo}{}%
\renewcommand{\@algocf@procname}{Procedimento}%
\renewcommand{\@algocf@funcname}{Fun\c{c}\~{a}o}%
\renewcommand{\procedureautorefname}{procedimento}%
\renewcommand{\functionautorefname}{fun\c{c}\~{a}o}%
\renewcommand{\algocf@languagechoosen}{portuguese}%
}%

If your language is not supported here, you can perform the manual redefinitions yourself using a similar setup to the language settings above. If you just have a couple of changes that doesn't affect many components of your document, using

\renewcommand{\algorithmcfname}{Algoritme}% Afrikaans "Algorithm"

should work. You may also want to define your keywords accordingly.
