Interface Problem<T,G extends Gene<?,G>,C extends Comparable<? super C>>

Type Parameters:

T - the (native) argument type of the problem fitness function

G - the gene type the evolution engine is working with

C - the result type of the fitness function

public interface Problem<T,G extends Gene<?,G>,C extends Comparable<? super C>>

This interface describes a problem which can be solved by the GA evolution Engine. It connects the actual fitness() function and the needed codec().

Method Summary

Modifier and Type	Method and Description
Codec<T,G>	codec() Return the codec, which translates the types of the problem domain into types, which can be understand by the evolution Engine.
Function<T,C>	fitness() Return the fitness function of the problem in the native problem domain.
static <T,G extends Gene<?,G>,C extends Comparable<? super C>> Problem<T,G,C>	of(Function<T,C> fitness, Codec<T,G> codec) Return a new optimization problem with the given parameters.
