Detailed Description

template<class T, class E, class P>
class vita::constrained_evaluator< T, E, P >

The class merges a basic evaluator and a penalty function into a new combined evaluator.

Template Parameters

T	the type of individual used
E	the basic evaluator
P	the penalty function

The new evaluator calculates an augmented fitness of this form:

(-penalty, base fitness)
