evotorch.algorithms.cmaes.CMAES, which is simply a wrapper for pycma toevotorch.algorithms.pycmaes.PyCMAES.evotorch.algorithms.cmaes.CMAES. This aims to faithfully reimplement the most recent version of pycma, while also benefiting from the evotorch ecosystem e.g. vectorized, GPU based, working with torch tensors for compatibility with other features.evotorch.algorithms.restarters, which provides basic functionality for meta-algorithms that wrap around aSearchAlgorithmclass + parameterization, and allow automatic restarting of the algorithm. This creates basic functionality for the eventual re-implementation e.g. of IPOP-CMA-ES and BIPOP-CMA-ES, and equivalent algorithms for XNES, SNES etc.is_terminatedflag to allSearchAlgorithmclasses, that will allow the user to define their own general functionality for detecting termination states that should trigger restarts. Currently, this value defaults toFalse, but in the future it is intended to add example termination states to the newCMAESimplementation.
