WebDec 2, 2024 · The Hungarian algorithm can be used to solve this problem. Minimum Weight Matching. In a weighted bipartite graph, a matching is considered a minimum weight matching if the sum of weights of the matching is minimised. The Karp algorithm can be used to solve this problem. Running Examples WebThe Hungarian algorithm is based on the concept of augmenting paths to find ways to increase the matching [35]. Starting from the left set, each unmatched vertex is sequentially traversed in an attempt to match it with an unmatched vertex on the right. ...
