Kurzfassung

In this paper an evolution strategy for single- and multi-objective optimization is presented. The model uses the predator-prey approach from ecology to scale between both cases. Furthermore, the main issue of adaptation working for single- and multi-objective problem instances equally is discussed. Particular, the well proved self-adaptation mechanism for the mutation strengths in the single-objective case is adopted for the multi-objective one. This self-adaptation process is supported by a new strategy of competition between predators and preys. Six test functions are used to demonstrate the practicability of the model.
