Method Summary

Fitness	evaluate(Solution solution) Evaluate the fitness function with the indicated solution.
void	init(SBVRDescription description, FitnessFunctionContext context) Init this fitness funcion.

Method Detail

init

void init(SBVRDescription description,
          FitnessFunctionContext context)

Init this fitness funcion. At this moment, we can get any parameter from the FitnessFunctionContext of store this object in order to get the parameters later, at "evaluation" time. This will depend if we can perform all evaluations taking into account the "global system" progress or not.

Parameters:

description - The request that acts as the evaluation counterpart

context - The FitnessFunctionContext

evaluate

Fitness evaluate(Solution solution)

Evaluate the fitness function with the indicated solution.

Parameters:

solution - The Solution that should be evaluated

Returns:

fitness The calculated fitness value
