We study a natural generalization of the maximum weight many-to-one matching problem. We are given an undirected bipartite graph G = (A P, E) with weights on the edges in E, and with lower and upper quotas on the vertices in P.We seek a maximum weight many-to-one matching satisfying two sets of...

We are given a bipartite graph G = (A B;E) where each vertex has a preference list ranking its neighbors: in particular, every a A ranks its neighbors in a strict order of preference, whereas the preference list of any b B may contain ties. A matching M is popular if there is no matching M' such...
