Dynamic niching in evolution strategies with covariance matrix adaptation
Abstract- Evolutionary Algorithms (EAs) have the tendency to converge quickly into a single solution in the search space. However, many complex search problems require the identiļ¬...

Self-Adaptive Niching CMA-ES with Mahalanobis Metric
Existing niching techniques commonly use the Euclidean distance metric in the decision space for the classification of feasible solutions to the niches under formation. This approa...

Coevolutionary Genetic Algorithms to Simulate the Immune System's Gene Libraries Evolution
Two binary-encoded models describing some aspects of the coevolution between an artiļ¬cial immune system and a set of antigens have been proposed and analyzed. The ļ¬rst model ha...
