WebJan 1, 1997 · In this paper we present a genetic algorithm (GA)-based heuristic for solving the generalised assignment problem. The generalised assignment problem is the problem of finding the minimum cost assignment of n jobs to m agents such that each job is assigned to exactly one agent, subject to an agent's capacity. In addition to the standard … WebOnce the problem has been formulated as a set-covering, set-packing or set-partitioning problem, the search for an optimal (or near-optimal) solution to this NP -hard 0–1 linear programming problem remains. Most solution approaches start by considering the linear programming relaxation (LP relaxation) of the respective problem.
