I have AC using Bellman_Ford.
Algoritm needs some attention in adaptation.
But what your want just real work in verification
of your program. In other words specialist will
make comparison your code and all steps of right algorithm.
I thihk that is field for business.

Thanks, it was just a floating point error. After adding an Eps = 1e-5 I've got AC.

I'll catch you man :D
