About: Libcmaes is a multithreaded C++11 library (with Python bindings) for high performance blackbox stochastic optimization of difficult, possibly non-linear and non-convex functions, using the CMA-ES algorithm for Covariance Matrix Adaptation Evolution Strategy. Libcmaes is useful to minimize / maximize any function, without information regarding gradient or derivability.

Changes:

Small release with two bug fixes and tiny changes otherwise:

  • small API improvements

  • fixed bug in tolX stopping criteria when using 'sep' algorithm

  • fixed bug to the natural gradient with genotype /phenotype transforms

  • file stream now outputs parameter's mean in phenotype

  • tiny wrapper to simplify maximization of objective function (default is minimization)
