Problem Definition

Assume that a complete bipartite graph, G(X, Y, X × Y ), with weights w(x, y) assigned to every edge (x, y) is given. A matching M is a subset of edges so that no two edges in M have a common vertex. A perfect matching is one in which all the nodes are matched. Assume that \(\vert X\vert =\vert Y \vert = n\)
