[Tex/LaTex] How to localize label using algorithm and algorithmic packages

algorithmscaptionslanguagesnaming

I am writing a paper in Italian and I need to include pseudo code in my latex document so I am currently using the algorithm and algorithmic packages. At the top of every algorithm the label Algorithm 1 is shown, but I'd like for it to be in Italian instead. I have previously included:

\usepackage[italian]{babel}
\usepackage[utf8]{inputenc}

with no change whatsoever, is there any way to localize it?

\documentclass[a4paper,12pt]{article}
\usepackage{algorithm}
\usepackage{algorithmic}
\usepackage[italian]{babel}
\usepackage[utf8]{inputenc}
\title{ASD}
\author{haunted85}
\date{Ottobre 2012}
\begin{document}
\maketitle
\section{}
\begin{algorithm}
\caption{Questo è un algoritmo.}
\begin{algorithmic}[1]
\STATE int Count(int $N$)
\STATE $sum = 0$
\FOR{$i \leq N$}
\FOR{$j = i \leq N$}
\STATE $sum = sum + 1$
\ENDFOR
\ENDFOR
\RETURN $sum$
\end{algorithmic}
\end{algorithm}
\end{document}

Best Answer

Either use \floatname{algorithm}{Algoritmo} (see section 4.4 of the algorithms manual) or, if you want to be able to switch between Italian and English caption names, redefine \ALG@name using babel macros.

\documentclass{article}

\usepackage[english,italian]{babel}

\usepackage{algorithmic}
\usepackage{algorithm}

% Alternative A
% \floatname{algorithm}{Algoritmo}

% Alternative B
\makeatletter
\addto\captionsitalian{\renewcommand{\ALG@name}{Algoritmo}}
\addto\captionsenglish{\renewcommand{\ALG@name}{Algorithm}}
\makeatother

\begin{document}

\begin{algorithm}
\caption{An algorithm}
\begin{algorithmic}
\STATE Some text.
\end{algorithmic}
\end{algorithm}

\end{document}

[Tex/LaTex] program, algorithmic packages conflict

I see at least two solutions:

1) Instead of using algorithmic, use the algorithmicx package, which gives you more functionality and flexibility:

\documentclass{article}
\usepackage{algorithmicx,algpseudocode}
\usepackage{program}

\begin{document}

\begin{algorithmic}
\State a
\State b
\end{algorithmic}

\end{document}

2) Use the savesym package, and the technique I explained in Two conflicting packages in one document — doable? to prevent name clashes:

\documentclass{article}
\usepackage{savesym}
\usepackage{program}
\savesymbol{AND}
\savesymbol{OR}
\savesymbol{NOT}
\savesymbol{TO}
\savesymbol{COMMENT}
\savesymbol{BODY}
\savesymbol{IF}
\savesymbol{ELSE}
\savesymbol{ELSIF}
\savesymbol{FOR}
\savesymbol{WHILE}
\usepackage{algorithmic}

\begin{document}

\begin{algorithmic}
\STATE a
\STATE b
\end{algorithmic}

\end{document}

[Tex/LaTex] Changing label name for algorithm

For the sake of consistency, define a new environment that uses the MegaAlgorithm caption style. Not sure whether you will intermix regular Algorithms and MegaAlgorithms, which this solution is geared towards:

enter image description here

\documentclass{article}
\usepackage[ruled,vlined]{algorithm2e}

\newenvironment{megaalgorithm}[1][htb]
  {\renewcommand{\algorithmcfname}{MegaAlgorithm}% Update algorithm name
   \begin{algorithm}[#1]%
  }{\end{algorithm}}

\begin{document}
\begin{megaalgorithm}
  \DontPrintSemicolon
  \KwData{$G=(X,U)$ such that $G^{tc}$ is an order.}
  \KwResult{$G’=(X,V)$ with $V\subseteq U$ such that $G’^{tc}$ is an interval order.}
  \caption{\textsc{Fast}SLAM}
\end{megaalgorithm}
\begin{algorithm}
  \DontPrintSemicolon
  \KwData{$G=(X,U)$ such that $G^{tc}$ is an order.}
  \KwResult{$G’=(X,V)$ with $V\subseteq U$ such that $G’^{tc}$ is an interval order.}
  \caption{\textsc{Fast}SLAM}
\end{algorithm}
\end{document}

The new megaalgorithm environment redefines \algorithmcfname - the macro used to print the caption type - just before calling the regular algorithm environment. Since the redefinition is within the scope of megaalgorithm, it is localized and reverts back to the default afterwards. This allows you to intermix the different kinds of algorithm types.

If you wish to have a separate counter for MegaAlgorithm and Algorithm, you can use the following definition of megaalgorithm in your preamble:

\makeatletter
\newcounter{megaalgorithm}
\newenvironment{megaalgorithm}[1][htb]
  {\renewcommand{\algorithmcfname}{MegaAlgorithm}% Update algorithm name
   \let\c@algocf\c@megaalgorithm% Update algorithm counter
   \begin{algorithm}[#1]%
  }{\end{algorithm}}
\makeatother
