Summary[edit]

Description
English: Meta-optimization progress of finding good behavioural parameters NP and F of Differential Evolution (DE) with a fixed parameter CR = 0.9, when DE is used for optimizing several benchmark problems problems in aggregate. Lines show moves made by the meta-optimizer (the method Local Unimodal Sampling, or LUS, is being used as meta-optimizer), crosses show moves contemplated but not taken as they would lead to worse meta-fitness. These are superimposed on the meta-fitness or performance landscape to show the valley of good performing parameters is actually found.
