WebOne of the classical combinatorial optimization problems is finding a maximum matching in a bipartite graph. The bipartite matching problem enjoys numerous practical applications [2, Section 12.2], and many efficient, polynomial time algorithms for computing solutions [8] [12] [14]. Formally, a bipartite graph is a graphG= (U [V;E) in whichE µ U £V. WebFor example, a ride-hailing service may use it to nd the optimal assignment of drivers to passengers to minimize the overall wait time. Typically, given two bipartite sets, this process involves com-puting the edge costs between all bipartite pairs and nding an optimal matching. However, existing works overlook the impact of

WebBipartite Matching matching, is used to determine the maximum matching on G.
