# [Tex/LaTex] Algorithm with Latex ( Package algorithmicx)

algorithmicx

This is my algorithm:

 \usepackage{graphicx}
\usepackage[linesnumbered,ruled,vlined]{algorithm2e}
\usepackage{algorithmicx}
\usepackage{algpseudocode}
%\usepackage{algorithmic}
\usepackage{float}
\begin{document}
\begin{algorithm}
\caption{Euclid's algorithm}\label{euclid}
\begin{algorithmic}[1]
\Procedure{Euclid}{$a,b$}
\State $r\gets a\bmod b$
\While{$r\not=0$}
\State $a\gets b$
\State $b\gets r$
\State $r\gets a\bmod b$
\EndWhile
\State \textbf{return} $b$\Comment{The gcd is b}
%\EndProcedure
\end{algorithmic}
\end{algorithm}
\end{document}


i have this error:

./llncs1.dem: 102: Missing number, treated as zero /EndWhile


Have you an idea please ?

You could simply do this:

\documentclass{article}
\usepackage{algorithm} %ctan.org\pkg\algorithms
\usepackage{algpseudocode}
\begin{document}

\begin{algorithm}
\begin{algorithmic}[1]
\Procedure{Euclid}{$a,b$}
\State $r\gets a\bmod b$
\While{$r\not=0$}
\State $a\gets b$
\State $b\gets r$
\State $r\gets a\bmod b$
\EndWhile
\State \textbf{return} $b$ \Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\caption{Euclid's algorithm}
\label{euclid}
\end{algorithm}

\end{document}


Some packages define these kinds of floating environments, like alg, but that conflicted also.
