Meta-evolved empirical evidence of the effectiveness of dynamic parameters
Brian W. Goldman, Daniel R. Tauritz · 2011
Traditional evolutionary algorithms (EAs) are powerful problem solvers that have several fixed parameters which require tuning. An increasing body of evidence suggests that the optimal values of some, if not all, EA parameters change during the course of executing an evolutionary run. This paper investigates the potential benefits of dynamic parameters by applying a Meta-EA to evolving optimal dynamic parameter values for population size, offspring size, n in n-point crossover, Gaussian mutation's step size, bit flip mutation's mutation rate, parent selection tournament size, and survivor selection tournament size.
