Hi Cristoforo. I don't want all combinations. I only want paths. For example, from node 0 only two paths are possible - 0-200 and 0-1800. So to go from 0-2000 there are only, (0-200,200-400,400-600,600-800,800-1000,1000-2000),
(0-1800,1000-2000)
and (0-200,0-1800,1000-2000)
which is what i want my program to output.
