source code

TransformSearchSpace(f, s)(x) == f(s(x))

>>> import cma
>>> f0 = lambda x: sum(x)
>>> shift_fct = cma.ConstRandnShift()
>>> f = cma.FF2.TransformSearchSpace(f0, shift_fct)
>>> x = [1, 2, 3]
>>> assert f(x) == f0(shift_fct(x))

Parameters:

fitness_function - a callable object
multipliers - recycling is not implemented, i.e. the dimension must fit to the fitness_function argument when called

Overrides: object.__init__
