Constrained matching problems in bipartite graphs

M Mastrolilli, G Stamoulis - International Symposium on Combinatorial …, 2012 - Springer
We study the following generalization of maximum matchings in bipartite graphs: given a
bipartite graph such that each edge has a unique color cj, we are asked to find a maximum …
