algorithmicalgorithms
This is my algorithm:
\usepackage{algorithm}
\usepackage{algorithmic}
\begin{document}
\begin{algorithm}[H]
\caption{My algo}
\begin{algorithmic}[1]
\STATE instruction 1
\STATE instruction 2
\end{algorithmic}
\end{algorithm}
\end{document}
How can I specify which instruction have applied this option: [1] ?
I'd like to delete the number before "Début" and before "Fin", I'd like also add spacing before "ch" and "po"
The IEEEtran's documentation suggests:
B. Algorithms
IEEE publications use the
figureenvironment to containalgorithmsthat are not to be a part of the main text flow. Peter Williams’ and Rogerio Brito’salgorithmic.stypackage [24] or Szász János’algorithmicx.stypackage [25] (the latter is designed to be more customizable than the former) may be of help in producing algorithm-like structures (although authors are of course free to use whatever LaTeX commands they are most comfortable with in this regard). However, do not use the floatingalgorithmenvironment ofalgorithm.sty(also by Williams and Brito) oralgorithm2e.sty(by Christophe Fiorio) as the only floating structures IEEE uses arefigures andtables. Furthermore, IEEEtran will not be in control of the (non-IEEE) caption style produced by thealgorithm.styoralgorithm2e.styfloat environments.
So, as suggested, do not use the algorithm floating environment; you can wrap your algorithm inside a figure (or figure*) environment (if a caption is required and the captions are to be IEEEtran compliant) and use the algorithmicx package ; something like this:
\documentclass{IEEEtran}
\usepackage{algpseudocode}
\begin{document}
\begin{figure}
\begin{algorithmic}[1]
\Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
\State $r\gets a\bmod b$
\While{$r\not=0$}\Comment{We have the answer if r is 0}
\State $a\gets b$
\State $b\gets r$
\State $r\gets a\bmod b$
\EndWhile\label{euclidendwhile}
\State \textbf{return} $b$\Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\caption{Euclid's algorithm}\label{euclid}
\end{figure}
\end{document}
If no caption is required, then simply don't use the figure environment.
set \setstretch{1.4} to any value you like
\documentclass{article}
\usepackage{algorithm}
\usepackage{algorithmic}
\usepackage{setspace}
\let\Algorithm\algorithm
\renewcommand\algorithm[1][]{\Algorithm[#1]\setstretch{1.4}}
\begin{document}
\begin{algorithm}[H]
\caption{My algo}
\begin{algorithmic}[1]
\STATE instruction 1
\STATE instruction 2
\end{algorithmic}
\end{algorithm}
\end{document}

The optional argument to
algorithmic([1]in this case), provides the line numbered at every line. A numbering modulo 2 would be obtained using[2], and so forth.Here's a slight variation of Is it possible to have connecting loop lines (like
algorithm2e) inalgorithmic? - usingalgpseudocode(fromalgorithmicx) - to insert Début and Fin as keywords. Others still need to be translated to French:\Stateprovides a "regular line" (with number), while\Statexprovides an unnumbered line. As such, I've defined both Début and Fin to be of\Statex.Adding the macro
allows you to print an unnumbered line. Now you can use it as follows:
