Approximating maximum weight - ScienceDirect

WebWe will use A (S) to represent the maximum weight of an independent set in the subgraph induced by the vertices in S. The algorithm is as follows: Initialize A ( {}) = 0 and A ( {i}) = w (i) for all vertices i in G. For all sets S with at least two vertices, compute A (S) as follows: a. If vertex n is not in S, then A (S) = A (S- {n}). b. WebReduction from the maximum clique problem shows that this problem is NP-hard. The weighted version of DS-kin which each edge has a positive weight and the goal is to maximize the sum of edge weights in the induced subgraph is called the heaviest k-subgraph problem (HS-k).
