Recently, gradient techniques for solving numerical multi-objective optimization problems have appeared in the literature. Although promising results have already been obtained when combined with multi-objective evolutionary algorithms (MOEAs), an important question remains: what is the best way to integrate the use of gradient techniques in the evolutionary cycle of a MOEA. In this paper, we present an adaptive resource-allocation scheme that uses three gradient techniques in addition to the variation operator in a MOEA. During optimization, the effectivity of the gradient techniques is monitored and the available computational resources are redistributed to allow the (currently) most effective operator to spend the most resources. In addition, we indicate how the multi-objective search can be stimulated to also search $mboxemphalong $ the Pareto front, ultimately resulting in a better and wider spread of solutions. We perform tests on a few well-known benchmark problems as well as two novel benchmark problems with specific gradient properties. We compare the results of our adaptive resource-allocation scheme with the same MOEA without the use of gradient techniques and a scheme in which resource allocation is constant. The results show that our proposed adaptive resource-allocation scheme makes proper use of the gradient techniques only when required and thereby leads to results that are close to the best results that can be obtained by fine-tuning the resource allocation for a specific problem.
