keep and update a termination condition dictionary, which is "usually" empty and returned by CMAEvolutionStrategy.stop(). The class methods entirely depend on CMAEvolutionStrategy class attributes.

Details

This class is not relevant for the end-user and could be a nested class, but nested classes cannot be serialized.

Example

>>> import cma
>>> es = cma.CMAEvolutionStrategy(4 * [1], 1, {'verbose':-1})
>>> print(es.stop())
{}
>>> es.optimize(cma.fcts.sphere, verb_disp=0)
>>> print(es.stop())
{'tolfun': 1e-11}
