Minimum weight maximum matching

Web20 sep. 2024 · Find a maximum weighted matching M by running hungarian(G, w′) Since the left unmatched vertices should choose their minimum weighted edge respectively, the total cost is ∑(v ∈ V) c_min(v) - w′(M) Step 1 and 2 traverses the graph twice and once separately, each takes O( E ) time. Step 3 using hungarian algorithm requires O( V ^3) time.
