In order to investigate the phenomena involved in the GA population evolution, the crossover is exposed to excitation perturbations and the corresponding fitness variations are evaluated. The input/output signals are studied revealing a fractional-order dynamic evolution, characteristic of a long-term system memory.engFractional OrderJoint TorqueCrossover ProbabilityEstimate PoleWhite Noise Signalconference object10.1007/3-540-45105-6_63
