cma.constraints_handler.PopulationEvaluator

class documentation

class PopulationEvaluator(object):

evaluate and store f- and g-values of a population in attributes F and G.

If the g-function (constraints) has an insert method, x-values are "inserted" first.

If the constraints function has a true_g attribute (assigned during the call) and offset_from_true_g is True, population constraints values are corrected by an offset to guaranty that g >= 0 if true_g > 0. Named solutions are not offset.
