        FFWrapper

A collection of (yet experimental) classes to implement fitness transformations and wrappers. Aliased to FF2 below.

Nested Classes

[hide private]

FitnessTransformation
This class does nothing but serve as an interface template. Typical use-case:

BookKeeping
a stump for experimenting with use-cases and possible extensions of book keeping

TransformSearchSpace
constructs the composed function f <- f o shift.

ScaleCoordinates
define a scaling of each variable

ShiftedFitness
f = cma.ShiftedFitness(cma.fcts.sphere) constructs a shifted sphere function, by default the shift is computed from class ConstRandnShift with std dev 3.

RotatedFitness
f = cma.RotatedFitness(cma.fcts.elli) constructs a rotated ellipsoid function

FixVariables
fix variables to given values, thereby reducing the dimensionality of the preimage.

SomeNaNFitness

NoisyFitness
apply noise via f += rel_noise(dim) * f + abs_noise()

GlueArguments
f = cma.FF2.GlueArguments(cma.fcts.elli, cond=1e4)

UnknownFF
search in [-10, 10] for the unknown (optimum)
