There was a bug in bipartite matching example. Bug 1. The random always returns the same number with default seed.
Bug 2. Below is a complete bipartite graph with two vertices on both left and right hand sides. "A L:B D" "B R:A C" "C L:B D" "D R:A C" Therefore, randomized matching results always can be different. I've committed my changes. If I missed something, Pls let me know. -- Best Regards, Edward J. Yoon @eddieyoon
