Abstract: |
We present an experimental study that shows a relationship between thedynamics of the environment and the adaptation of strategy parameters.Experiments conducted on two adaptive evolutionary strategies SA-ES andCMA-ES on the dynamic sphere function, show that the nature of themovements of the function's optimum are reflected in the evolution of the mutation steps. Three types of movements are presented: constant,linear and quadratic velocity, in all, the evolution of mutation stepsduring adaptation reflect distinctly the nature of the movements.Furthermore with CMA-ES, the direction of movement of the optimum canbe extracted. |
