Detailed Description

template<class T>
class gal::Problem< T >

Contains information on the problem that is to be solved with GA.

A gal::Population requires an instance of a subclass of gal::Problem. Both the objective function and some representation-related functions are relevant.

You always need to use a subclass of this class, where all virtual functions below are defined.

Member Function Documentation

template<class T> virtual Chromosome<T>* const gal::Problem< T >::constructChromosome (  int  chromoLength  )  [pure virtual]

Returns a new Chromosome<T>. Usually this will be an instance of *a subclass of* Chromosome<T>. Implemented in gal::MaxIntProblem.

template<class T> virtual Chromosome<T>* const gal::Problem< T >::copyChromosome (  Chromosome< T > *  chromo  )  [pure virtual]

Returns a new Chromosome<T>, which is a copy of the specified chromosome. Usually this will be an instance of *a subclass of* Chromosome<T>. (necessary, because static typing makes a copy constructor impossible) Implemented in gal::MaxIntProblem.

template<class T> virtual void const gal::Problem< T >::deleteChromosome (  Chromosome< T > *  chromo  )  [pure virtual]

Deletes a Chromosome<T>* Usually this will be an instance of *a subclass of* Chromosome<T>. (necessary, because static typing would otherwise default to the superclass's destructor, and would then result in a memory leak.) Implemented in gal::MaxIntProblem.

template<class T> virtual double const gal::Problem< T >::evaluateObjective (  Chromosome< T > *  chromo  )  [pure virtual]

Evaluates the objective function for the value that a chromosome represents. Implemented in gal::MaxIntProblem.
