A modified version of a T-Cell Algorithm for constrained optimization problems

In this paper, we present a heuristic inspired on the T-Cell model of the immune system (i.e. an artificial immune system). The proposed approach (called T-Cell) is used for solving constrained (numerical) optimization problems, and is validated using several test functions taken from the specialized literature on evolutionary optimization. Additionally, several engineering optimization problems are also used for assessing the performance of the proposed approach. The results are compared with respect to approaches representative of the state-of-the-art in constrained evolutionary optimization. Copyright (C) 2010 John Wiley & Sons, Ltd.
