WebAug 5, 2024 · This paper proposes GAP, a Genetic Algorithm based graph Partitioning algorithm to solve this problem. GAP aims to reduce the total processing time on a heterogeneous cluster by partitioning graphs according to the computing powers of computing nodes. Web3 A Genetic Algorithm for the Top-k-s-club Problem As reported above, the Top-k-2-clubs is NP-hard, thus making optimization potentially impracticable. Our approach here is to provide approximate solutions by designing de- dicated genetic operators. Let G[V 0 ] be a 2-club of the input graph G = (V, E), for some set of vertices V 0 ⊆ V . phoenix tour band
