Question

Let G = (V,E) be a bipartite graph, but this time it is a weighted graph. The weight of a
complete matching is the sum of the weights of its edges. We are interested in finding a
minimum-weight complete matching in G.
a) Give a legitimate C for a branch-and-bound (B&B) algorithm that finds a minimum-weight
complete matching in G, and prove that your C is valid. Your C cannot be just the cost so
far.
b) Using your C, apply B&B to find a minimum-weight complete matching in the following
weighted bipartite graph G: A = (1,2,3), B = (4,5,6,7)
E = (((1,4), 3]. [(1,5), 4]. [(1,7). 15]. ((2,4), 1]. |(2,5), 8]. [(2,6), 3]. |(3,4), 3]. [(3,5), 9]. [ (3,6). 51).
Show the solution tree. the C of every tree node generated, and the optimal solution. Also,
mark the order in which each node in the solution tree is visited.
