Differential evolution,jSO,strategy,competition,real-world problems

A newly proposed variant of the efficient jSO algorithm employing competition of eight strategies (cSO) is proposed. The main idea is to select the most proper strategy and adapt the setting to each solved problem. One more mutation variant and one more type of crossover are added to jSO, and moreover, the popular mechanism of Eigen coordi- nate system is applied. All eight strategies compete to be used in the next generations based on the successes in previous generations. The proposed cSO method has more wins over jSO significantly in more real-world problems than fails. The original jSO strategy is never the most frequently used strategy, compared with other newly employed strategies.
