bipartite realization problem : ウィキペディア英語版 | bipartite realization problem The bipartite realization problem is a classical decision problem in graph theory, a branch of combinatorics. Given two finite sequences and of natural numbers, the problem asks whether there is labeled simple bipartite graph such that is the degree sequence of this bipartite graph. ==Solutions== The problem belongs to the complexity class P. This can be proven using the Gale–Ryser theorem, i.e. one has to validate the correctness of inequalities.
