| Research Abstract |
In our research, we developed high-performance metaheuristic algorithms called memetic algorithms for combinatorial optimization problems. As combinatorial optimization problems, we deal with the Maximum Clique Problem(MCP), Quadratic Assignment Problem(QAP), and Node Placement Problem(NPP), which are known to be NP-hard. Particularly, for the QAP, we show an effective metaheuristic algorithm called genetic iterated local search(GILS) incorporating k-opt local search based on the idea of variable depth search. Computational results showed that the GILS with KLS obtained good results on average in comparison to standard iterated local search metaheuristic algorithms for the QAP.
