Description:

libcmaes is a multithreaded C++ implementation of the CMA-ES algorithm for stochastic optimization of nonlinear 'blackbox' functions. The implemented algorithms have a wide range of applications in various disciplines, ranging from pure function optimization, optimization in industrial and scientific applications, to the solving of reinforcement and machine learning problems.

Current features include: high-level API for simple use in external applications, implementatio of several flavors of CMA-ES, IPOP-CMA-ES, BIPOP-CMA-ES, active CMA-ES, active IPOP and BIPOP restart strategies, sep-CMA-ES (linear time & space complexity) along with support for IPOP and BIPOP flavors as well.

Some operations benefit from multicores, and there's support for objective function gradient, when available. A control exe in the command line is provided for running the algorithm over a range of classical single-objective optimization problems.

Changes to previous version:

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)
