cma.fitness_transformations

module documentation

Wrapper for objective functions like noise, rotation, gluing args

Class ComposedFunction compose an arbitrary number of functions.
Class Expensify Add waiting time to each evaluation, to simulate "expensive" behavior
Class FBoundTransform shortcut for ComposedFunction([f, BoundTransform(bounds).transform]), see also below.
Class FixVariables Insert variables with given values, thereby reducing the dimensionality of the resulting composed function.
Class Function a declarative base class, indicating that a derived class instance "is" a (fitness/objective) function.
Class GlueArguments deprecated, use functools.partial or cma.fitness_transformations.partial instead, which has the same functionality and interface.
Class IntegerMixedFunction DEPRECATED compose fitness function with some integer variables using np.floor by default.
Class IntegerMixedFunction2 compose fitness function with some integer variables using np.round by default.
Class NoisyFitness apply noise via f += rel_noise(dim) * f + abs_noise(dim)
Class Rotated return a rotated version of a function for testing purpose.
Class ScaleCoordinates compose a (fitness) function with a preceding scaling and offset.
Class Shifted compose a function with a shift in x-space.
Class SomeNaNFitness transform fitness_function to return sometimes NaN
Class StackFunction a function that returns f1(x[:n1]) + f2(x[n1:]).
