It's working very well. I have very few and minor comments

Hello! Replying to @dcoudert:
Done!
Done! I used the first link.
Done!
Done!
Not done! In my opinion, it has impact on the computation time. Indeed, when we fix a pair (a,b), the algorithm does the following:
Here, the first for loop is performed as many times as the number of vertices satisfying The last loop takes time 10, as it is, while it takes time 10000 if we use memset (I know memset is very fast, but here we are talking about two orders of magnitude). Did I convince you? |

This is weird. I have tried both on a 64bits and a 32 bits computer all the graphs for which we have the list of edges and my computers reports no error. David. |

Hello! This problem was that I forgot to set h=0 at the beginning... Now it should work! Michele |

The patch passes all tests on both my mac (64bits) and a 32bits linux PC. |
