1. (25) [Set packing and independent set] Prove or disprove that INDEPENDENT-SET-p SET-PACKING, that is, these two problems are computationally equally hard. Feel free to use an illustration if it helps. The definitions of these two decision problems are summarized below We already proved that INDEPENDENT-SET 3p SET-PACKING, so assume this as given. INDEPENDENT-SET: Given a graph G = (V, E) and an integer k, is there a subset of vertices S c V such that |S|2 k and, for each edge in E, at most one - but not both - of its end nodes is in S? . SET-PACKING: Given a set U of elements, a set of subsets Si, S2,. . . , Sm o integer k, does there exist a set of at least k subsets that are pairwise disjoint (i.e., intersection between every pair)
