      <td nosave="">How to symmetrize the graph:
       NONE = graph is symmetric and no symmetrization is needed <br/>
       TRANSPOSE = if M is adjacency matrix of the input graph, output will be the graph representation of M+M<sup>T</sup> <br/>
       BIPARTITE = graph is symmetrized in a bipartite way : [[ 0 M ][M<sup>t</sup> 0]]
