\begin{block}{Iteration Graph}
The {\emph{iteration graph}} $\Gamma(f)$: 
directed graph s. t.  
\begin{itemize}
\item the set of vertices: $\Bool^n$
\item the set of edges: $(x,F_f(i,x)) \in \Gamma(f)$, $x\in\Bool^n$, 
$i\in \llbracket1;n\rrbracket$
\end{itemize}
\end{block}

\begin{block}{Markov Matrix}
Matrix $M$: 
\[
\begin{array}{l}
M_{ij} = \frac{1}{n} \textrm{ if $i \neq j$ and $(i,j) \in  \Gamma(f)$} \\
M_{ij} = 0 \textrm{ if $i \neq j$ and $(i,j) \not \in  \Gamma(f)$} \\
M_{ii} = 1 - \sum\limits_{j=1, j\neq i}^n M_{ij}
\end{array}
\]
