algorithm2e
In the following MWE, I would like the end of switch to be different from the ends of case and other. Is it possible ?
\documentclass{article}
\usepackage{algorithm2e}
\begin{document}
\begin{algorithm}
\Begin{
\Switch{X}{
\Case{1}{
\While{Continue}{Action}
}
\Other{Other}
}
}
\end{algorithm}
\end{document}
There is an incompatibility between the algorithm2e/algorithmic packages and revtex4-1; one possibility is to use algcompatible instead of algorithmic (the syntax of the commands is the same and this solves the indentation problem) and to use the newfloat package to define a new algorithm float. Here's an example illustrating this approach (I used a table and a figure environments to show how the newly defined float behaves consistently with the class):
\documentclass{revtex4-1}
\usepackage{algcompatible}
\usepackage{newfloat}
\DeclareFloatingEnvironment[
fileext=loa,
listname=List of Algorithms,
name=ALGORITHM,
placement=tbhp,
]{algorithm}
\begin{document}
\begin{figure}
\rule{2cm}{2cm}
\caption{A test caption for a figure}
\end{figure}
\begin{table}
\rule{2cm}{2cm}
\caption{A test caption for a table}
\end{table}
\begin{algorithm}
\begin{algorithmic}
\FOR{every thing you}
\FOR{every step you}
\STATE{compute something}
\ENDFOR
\ENDFOR
\end{algorithmic}
\caption{Calculate something}
\end{algorithm}
\end{document}
If one wants to keep the ruled style of the algorithm environmet, as defined in algorithm2e, some additional work has to be done; in this case, the caption package could be used (providing one makes the necessary adjustments to recover the formatting defined in revtex4-1); here's such possibility with a little example:
\documentclass{revtex4-1}
\usepackage{newfloat,algcompatible}
\usepackage[size=small]{caption}
\usepackage{etoolbox}
\AtBeginEnvironment{algorithm}{\noindent\hrulefill\par\nobreak\vskip-5pt}
\usepackage{newfloat}
\DeclareFloatingEnvironment[
fileext=loa,
listname=List of Algorithms,
name=ALGORITHM,
placement=tbhp,
]{algorithm}
\DeclareCaptionFormat{algorithms}{\vskip-15pt\hrulefill\par#1#2#3\vskip-6pt\hrulefill}
\captionsetup[algorithm]{singlelinecheck=off,format=algorithms}
\begin{document}
\begin{figure}
\rule{2cm}{2cm}
\caption{A test caption for a figure}
\end{figure}
\begin{algorithm}
\begin{algorithmic}
\FOR{every thing you}
\FOR{every step you}
\STATE{compute something}
\ENDFOR
\ENDFOR
\end{algorithmic}
\caption{Calculate something}
\end{algorithm}
\end{document}
If, for some reason, the newfloat packageis not available, one can use the trivfloat instead:
\documentclass{revtex4-1}
\usepackage{algcompatible}
\usepackage[floatrow]{trivfloat}
\trivfloat{algorithm}
\renewcommand\algorithmname{ALGORITHM}
\begin{document}
\begin{figure}
\rule{2cm}{2cm}
\caption{A test caption for a figure}
\end{figure}
\begin{table}
\rule{2cm}{2cm}
\caption{A test caption for a table}
\end{table}
\begin{algorithm}
\begin{algorithmic}
\FOR{every thing you}
\FOR{every step you}
\STATE{compute something}
\ENDFOR
\ENDFOR
\end{algorithmic}
\caption{Calculate something}
\end{algorithm}
\end{document}
When you load algorithm2e with linesnumbered, it executes \nl at every paragraph break (taken from algorithm2e.sty):
%
% line numbering
%
\newcommand{\LinesNumbered}{%
\setboolean{algocf@linesnumbered}{true}%
\renewcommand{\algocf@linesnumbered}{\everypar={\nl}}}%
So, \nl is the thing we are interested in adjusting.
You can remove the line number for a single line using the following \nonl command:
\let\oldnl\nl% Store \nl in \oldnl
\newcommand{\nonl}{\renewcommand{\nl}{\let\nl\oldnl}}% Remove line number for one line
Here's a minimal example showing the output:
\documentclass{article}
\usepackage[linesnumbered]{algorithm2e}% http://ctan.org/pkg/algorithm2e
\makeatletter
\newcommand{\nosemic}{\renewcommand{\@endalgocfline}{\relax}}% Drop semi-colon ;
\newcommand{\dosemic}{\renewcommand{\@endalgocfline}{\algocf@endline}}% Reinstate semi-colon ;
\newcommand{\pushline}{\Indp}% Indent
\newcommand{\popline}{\Indm\dosemic}% Undent
\let\oldnl\nl% Store \nl in \oldnl
\newcommand{\nonl}{\renewcommand{\nl}{\let\nl\oldnl}}% Remove line number for one line
\makeatother

\nonl redefines \nl for one usage. That usage is just to redefine itself to use the original form (a similar-style trick is used in Cunning (La)TeX tricks).

It appears to be easier to change it for Case than Otherwise, but this seems to work:
