Results obtained with benchmark deceptive problems show that together the two adapted operators, MWM-MDR, produced a robust version of MuGA. They are not the best in all the problems but had good performance in most of them. Tests performed with nondeceptive functions showed that the new operators did no compromise performance, as it should be expected by their design. It is important to highlight this integrated functioning of operators, since this is one of the most important features for an evolutionary algorithm (EA). A single operator of an EA is seldom a solution. It needs an adequate pairing with the other operators. Obtained results seem to confirm this.
