Method Detail

evaluateMapping

public Fitness evaluateMapping(Matrix<Double> dist)

Implements the evaluateMapping function as required by NonlinearMappingProblem.

Specified by:

evaluateMapping in interface MappingEvaluator

Parameters:

dist - The distrance matrix for the generated output vectors.

Returns:

the fitness as a double, wrapped inside a Fitness.

setMappingProblem

public void setMappingProblem(MappingProblem prob)

Description copied from interface: MappingEvaluator

Gets called when attached to a MappingProblem. This is to allow one to call back to the problem in order to find additional info, such as the distance between vectors in the input.

Specified by:

setMappingProblem in interface MappingEvaluator

Parameters:

prob - The instance of MappingProblem that is going to use the evaluator.
