1. Max-Cut – problem definiton: Given an undirected graph G = (V,E), find a partition of the vertex set V = S ∪ S̄ that maximizes the number of cut-edges (edges with an endpoint in S and an endpoint in S̄). Examples: A clique, a bipartite graph, an odd cycle. The problem is NP-hard [7]. Can be approximated within factor 1/2 [11]. Exercise 1: Show that local… CONTINUE READING
