In genetic algorithm (GA), 2-opt, a local search mechanism, is often used as as mutation operation for solving Traveling Salesman Problems (TSPs). The 2-opt mutation exchanges some edges of parents to generate new children. However, the operation of random edge inversion destroys some good edges in later convergence process. To solve this problem, an adaptive 2-opt operation is proposed. The probability...
In this paper we proposed a new algorithm based on inver-over operator, for combinatorial optimization problems. Inver-over is based on simple inversion; however, knowledge taken from other individuals in the population influences its action. In the new algorithm we use some new strategies including selection operator, replace operator and some new control strategy, which have been proved to be very...
