Method Detail

evaluateMapping

public Fitness evaluateMapping(Matrix<Double> dist)

Implements the evaluateMapping function as required by.

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.

f

protected double f(double o)

The function F. Well, that is at least the name in the assignment that I'm working on. The only description I've got of this is "Where F is a decreasing function of o_ij." This is probably another candidate for subclassing.

Parameters:

o - The value to apply the function to.

Returns:

A value that decreases as o increases, never reaching 0.

setMappingProblem

public void setMappingProblem(MappingProblem prob)

Called by MappingProblem.setEvaluator in order to establisg bi-directional communication.

Specified by:

setMappingProblem in interface MappingEvaluator

Parameters:

prob - The instance of MappingProblem that is going use us.
