How to escape traps using clonal selection algorithms

ABSTRACT: The paper presents an experimental study on clonal selection algorithms (CSAs) to optimize simple and complex trap functions. Have been tested several setting of the proposed immune algorithms to effectively face this no easy computational problem. The key feature to solve the trap functions, hence escape traps, is the usage of the hypermacromutation operator couple with a traditional perturbation immune operator, the inversely proportional to the fitness function values hypermutation operator or the static hypermutation. The experimental results show that CSAs we designed is very competitive with the best algorithm in literature.
