Abstract

In this paper we examine an extension of the core concept for the 0/1 Multidimensional Knapsack Problem (MKP) towards general 0/1 Integer Programming (IP) by allowing negative profits, weights and capacities. The core concept provides opportunities for heuristically solving the MKP, achieving higher quality solutions and shorter runtimes than general IP methods. We provide the theoretical foundations of the extended core concept and further provide computational experiments showing that we can achieve similar computational behavior for extended MKP instances with negative weights, profits and capacities.
