Proceedings ArticleDOI
Comparing results of 31 algorithms from the black-box optimization benchmarking BBOB-2009
TL;DR: Results of the BBOB-2009 benchmarking of 31 search algorithms on 24 noiseless functions in a black-box optimization scenario in continuous domain are presented and the choice of the best algorithm depends remarkably on the available budget of function evaluations.
Proceedings ArticleDOI
Real-parameter optimization using the mutation step co-evolution
TL;DR: The algorithm described herein is tested on a suite of 10D and 30D reference optimization problems collected for the special session on real-parameter optimization of the IEEE Congress on Evolutionary Computation 2005.
Journal ArticleDOI
A comparison of global search algorithms for continuous black box optimization
TL;DR: Four methods for global numerical black box optimization with origins in the mathematical programming community are described and experimentally compared with the state of the art evolutionary method, BIPOP-CMA-ES and suggestions about which algorithm should be used depending on the available budget of function evaluations are drawn.
Book ChapterDOI
Preventing Premature Convergence in a Simple EDA Via Global Step Size Setting
TL;DR: It is shown that when isotropic distributions with Gaussian or Cauchy distributed norms are used, the simple constant setting of k is able to ensure a reasonable behaviour of the EDA on the slope and in the valley of the fitness function at the same time.
Proceedings ArticleDOI
BBOB-benchmarking a simple estimation of distribution algorithm with cauchy distribution
TL;DR: These tests prove that when using the Cauchy distribution and suitably chosen variance enlargment factor, the restarted estimation of distribution algorithm (EDA) is usable for broad range of fitness landscapes, which is not the case for EDA with Gaussian distribution which converges prematurely.
