I want to find 3 disjoint paths for each request (source node, destination node and required bandwidth). Now the constraints of one path have been listed. I only need to copy 3 copies of the constraints.
Now, if a request can't find 3 routes, it will have no solution.
I want it now to find 2 routes if it can't find 3 routes, and 1 path if it can't find 2 paths. How can I realize this?------------------------------
