In this paper a new electromagnetism-like mechanism is proposed for combinatorial optimization of capacitated vehicle routing problem. electromagnetism-like mechanism is a new metaheuristic method and inspired by the attraction and repulsion mechanism of the electromagnetism theory. we propose a new electromagnetism-like mechanism that it includes a new distance measure between solutions and new effective...
Job shop is one of a well known NP-hard optimization problems. In this paper, extremal optimization is proposed for job shop scheduling. Extremal optimization is an evolutionary meta-heuristic method that consecutively substitutes undesirable variables in current solution with a random value and evolves itself toward optimal solution. For EO, the quality of generated initial solution plays an important...
