math-mode
I'm getting that error for the line:
$S = (s_0,S), ahol s_0 = x_1 := <>,...,x_n := <> és S = \{x_0, x_1 := lorem(x_0), hiext(x_1,f_0(x_0.lov)), ha \ x_0 \not\equiv <> \\ ,...,$ \\
I'm very new to LaTeX, and don't quite understand what this means. Could you help?
You're not consistent with delimiting math formulas; for instance, in the second \STATE line, you open a math formula, without closing it.
I have tried to make the algorithms more consistent. Note that \LOOP and \Loop are not the same (and the latter is not defined in algorithmic). If you're using a different set of packages, please make it known.
\documentclass{article}
\usepackage{amsmath}
\usepackage{algorithm}
\usepackage{algorithmic}
\newcommand{\kw}[1]{\textrm{#1}}
\begin{document}
\begin{algorithm}
\caption{Algorithme de Dijkstra}
\begin{algorithmic}[1]
\REQUIRE Un graphe $G$
\REQUIRE Un noeud source $s$
\ENSURE Les plus court chemins de $s$ vers tout les autres noeuds de $G$ $A$
\FORALL{$v \in V[G]$}
\STATE $d[v] \leftarrow +\infty$
\STATE $\kw{previous}[v] \leftarrow \kw{undefined}$
\ENDFOR
\STATE $d[s] \leftarrow 0$
\STATE $S \leftarrow \kw{empty set}$
\STATE $Q \leftarrow V[G]$
\LOOP
\STATE $Q$ is not an empty set
\STATE $u \leftarrow \kw{Extract}_{\kw{Min}}(Q)$
\STATE $S \leftarrow S \cup \{u\}$
\FORALL{edge $(u,v)$ outgoing from $u$}
\IF{$d[u] + w(u,v) < d[v]$}
\STATE $d[v] \leftarrow d[u] + w(u,v)$
\STATE $\kw{previous}[v] := u$
\ENDIF
\ENDFOR
\ENDLOOP
\end{algorithmic}
\end{algorithm}
\end{document}

You have to use
\acute{e}instead oféin math mode, but I think it depends on your inputenc.I don't have that error and your code works fine (even if is a too long line in math mode with no breaks).
