[en] INTEGRATING METAHEURISTICS WITH MIP SOLVERS TO THE CAPACITATED VEHICLE ROUTING PROBLEM

[pt] Desde a sua origem, as abordagens a problemas de Otimização Combinatória polarizam-se entre métodos exatos e heurísticos. Recentemente, porém, estratégias que combinam ambos os métodos têm sido propostas para os mais variados problemas, apresentando resultados promissores. Nesse contexto, desta...
