public interface EvaluativeAlgorithm
extends AlgorithmicTemplate

Interface for evaluative algorithms.

This interface provides unified access to an evaluation function (to minimize etc.) while processing.

In order to transform a maximization problem into a minimization problem use the evaluation function -f instead of f.
