Generalized evolutionary programming with Levy-type mutation
A new generalized evolutionary programming with Levy-type mutation is proposed. The Levy-type distribution is know to reproduce Gaussian, Cauchy, and Student's t-distributions and characterized by a power-law fat-tail. This new evolutionary programming is tested for five standard test functions. The average performance of the new algorithm with Levy-type mutation for hard optimization problems is superior to the original evolutionary programming with Gaussian mutation.
