+ \subsection{Shared Synteny based Metric}
+ Given two genomes abstracted as sequences of classes, it is classical
+ to computes all the maximum shared synteny chains. 
+ 
+ % Attention ici, moins il y a de diff, plus le nombre est élevé
+ There are then three issues with such a set of shared synteny chains:
+ \begin{itemize}
+ \item let $m_{Y}$ be the metric, which returns the 
+ length of the largest chains;
+ \item let $m_{\overline{Y}}$ be the metric, which returns the 
+ average length of synteny chains;
+ \item finally, let $m_{|Y|}$ be the metric, which returns the 
+ number of synteny chains.
+ \end{itemize}
