Exact Solution of the Quadratic Knapsack Problem

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. TīmeklisBinary Quadratic Program with Variable Partitioning Constraints. The binary quadratic program with variable partitioning constraints is a very general class of optimization problems that is very difficult to solve because of the nonconvexity and integrality of the variables and is ubiquitous, among others, in network design, computer vision, and … TīmeklisThere are totally M items.
