Alternative evaluation functions for the cyclic bandwidth sum problem.
European Journal of Operational Research(2019)
摘要
•Alternative evaluation functions for the cyclic bandwidth sum problem are introduced.•Their discrimination capacity, compatibility and guiding efficiency were assessed.•They boosted the search performance of two diferent implemented algorithms.•They can be deployed within other metaheuristics to improve their search capacity.•Iterated Local Search was able to establish 14 new upper bounds for this problem.
