Web16 dec. 2015 · We introduce the Partitioning Min–Max Weighted Matching Problem (PMMWM). •. PMMWM combines a maximum matching and a partitioning problem. •. Applications arise in the field of intermodal container terminals and sea ports. •. We prove strong NP-hardness of PMMWM. •. We present two heuristic frameworks and an … In computer science and graph theory, the maximum weight matching problem is the problem of finding, in a weighted graph, a matching in which the sum of weights is maximized. A special case of it is the assignment problem, in which the input is restricted to be a bipartite graph, and the matching constrained to be have cardinality that of the smaller of the two partitions. Another special case is the problem of finding a maximum cardinality matching on an … mercedes of west caldwell inventory
