In order to understand the role of crossover in differential evolution, theoretical analysis and comparative study of crossover in differential evolution are presented in this paper. Two new crossover methods, namely consecutive binomial crossover and non-consecutive exponential crossover, are designed. The probability distribution and expectation of crossover length for binomial and exponentia...

• Importance of the constraint handling operator even for box-constrained problems. Use percentage solutions generated outside domain as performance measure . Re-purposing stochastic objective function f0 studying algorithmic effects. Popular EC algorithms generate significant amounts infeasible solutions. Distribution percentages is nontrivial. This paper investigates how often popular configu...
