Kurzfassung

The new ICSPEA (Integrated CMA-SPEA) combines the superior mutation concept of the CMA-ES with the evaluation scheme of the SPEA2. The external archive that is used, and the assignment of internal single-objective fitness values in this algorithm allows for a multi-objective realization of the CMA-ES using a comma-strategy. The history of self adaptation in single- and multi-objective evolutionary algorithms is shortly summarized, the algorithm is described, and tests are done using benchmark functions showing that uniting the best concepts of two algorithms yields a new MOEA with advantageous features.
