摘要: Based on the theory of non-negative super martingales, convergence results are proven for adaptive (1, λ) - ES (i.e. with Gaussian mutations), and geometrical rates derived. In d-dimensional case (d > 1), algorithm studied here uses a different step-size update in each direction. However, critical value step-size, resulting rate do not depend dimension. Those discussed respect to previous works. Rigorous numerical investigations some 1-dimensional functions validate theoretical results. Trends future research indicated.
