Have you tried algorithm2e? –  Marc van Dongen Sep 29 '12 at 11:36
    
algorithm2e let me to write a pseudo algorithm ? because my algorithm is just a set of sentences, it is not a true algorithm.. –  researcher Sep 29 '12 at 11:53
    
    
See Werner's excellent answer at Print programs with its proper syntax. –  Peter Grill Sep 30 '12 at 8:35

As has been mentioned in a comment, the algorithm2e package gives you the desired layout:

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

\begin{document}

\begin{algorithm}
\Begin{
$V \longleftarrow U$\;
$S \longleftarrow \emptyset$\;
\For{$x\in X$}{
$NbSuccInS(x) \longleftarrow 0$\;
$NbPredInMin(x) \longleftarrow 0$\;
$NbPredNotInMin(x) \longleftarrow |ImPred(x)|$\;
  }
}
\caption{My Algorithm}
\label{alg:test}
\end{algorithm}

\end{document}

i have used your code but i don't have the line that connects begin to end. have you an idea please –  researcher Sep 30 '12 at 9:47
    
with \usepackage[ruled,vlined]{algorithm2e} i have resolved the problem –  researcher Sep 30 '12 at 9:56
    
Please i ask if it's possible to have this same format with package algorithmic, because i should use it –  researcher Sep 30 '12 at 17:29
    
@researcher You can do it with algorithmicx (notice the "x" at the end) which is much better, can do everything algorithmic does and they are compatible. See [this answer by Werner] to learn how to achieve the desired layout using algorithmicx. –  Gonzalo Medina Sep 30 '12 at 23:17
    
The function names don't look very pretty. $\textit{NbSuccInS}(x) \longleftarrow 0$ looks nice and informal. –  Marc van Dongen Apr 15 '13 at 13:33
