Tīmeklis2024. gada 1. jūl. · The Quadratic Knapsack Problem with Conflict Graphs (QKPCG) is a generalization of the QKP in which, as for the knapsack problem with conflict graph (see Part I (Cacchiani et al., 2024), Section 9), a given undirected graph G = (V, E) defines the pairs of incompatible items that cannot be simultaneously selected. Tīmeklis2016. gada 1. maijs · Instead, an edge weighted graph, whose vertices represent the knapsack items, induces a quadratic profit for every pair of items, which is adjacent in the graph. We show that the problem permits an FPTAS on graphs of bounded treewidth and a PTAS on planar graphs and more generally on H -minor free graphs.
