network either as a square adjacency matrix or a list
describing E interactions a->b: the first (resp. second) element is
the vector of the labels of a (resp. b), the third (optional) is
the vector of interaction weights.
iterfac
At each temperature of the simulated annealing
(SA), the program performs fN^2 individual-node updates (involving the
movement of a single node from one module to another) and fN
collective updates (involving the merging of two modules and the split
of a module). The number "f" is the iteration factor.
