In a preliminary part of this paper, we analyze the necessity of randomness in evolution strategies. We conclude to the necessity of ”continuous”-randomness, but with a restricted amount of random seeds, and apply this results to CMA-ES, a famous evolution strategy already based on the idea of derandomization, which uses random independent gaussian mutations. We here replace these random independent gaussian mutations by a quasi-random sample. The modification is very easy, computationally faster and the convergence is faster
