Detailed Description

Individual: generic Individual.

Generic individual to be used with evolutionary algorithms. It is extended by ga::Individual and gp::Individual to provide specific functions oriented towards Genetic Algorithms and Genetic Programming, respectively.

Member Function Documentation

virtual Individual* genetiK::Individual::copy (   )  const [pure virtual]

abstract copy function This function must be extended by sublcasses to perform copy. Returns: a copy of the individual See also: Individual(const Individual& individual) Implemented in genetiK::ga::Individual, genetiK::gp::Individual, and genetiK::gp::st::Individual.

virtual int genetiK::Individual::crossOver (  Individual *  i, Individual **  child1, Individual **  child2 )  [pure virtual]

abstract crossover Performs crossover between this and individual i, saving the resulting children in child1 and child2. Subclasses must override this method to perform actual crossover Parameters: i  the partner to use to perform crossover. child1  first child. child2  second child. Returns: 0 if the operation was successful See also: mutate(double mutationProbabilty) Implemented in genetiK::ga::Individual, genetiK::gp::Individual, and genetiK::gp::st::Individual.

virtual double genetiK::Individual::fitness (   )  [pure virtual]

abstract fitness function This function must be extended by sublcasses to calculate the fitness of the individual. Returns: the fitness of the current individual Implemented in genetiK::ga::Individual, genetiK::gp::Individual, and genetiK::gp::st::Individual.

virtual int genetiK::Individual::mutate (  const double  mutationProbability  )  [pure virtual]

abstract mutation Must be overridden in subclasses to perform actual mutation. Parameters: mutationProbability  the probability that mutation occurs Returns: 0 if the operation was successful See also: crossOver Implemented in genetiK::ga::Individual, genetiK::gp::Individual, and genetiK::gp::st::Individual.

virtual bool genetiK::Individual::operator< (  Individual &  i2  )  [inline, virtual]

compares fitness between individuals Defines an total order relation among Individuals using their fitness. Parameters: i2  the individual to use in the comparison Returns: true if this Individual has a fitness that is less than i2's one See also: fitness()

string genetiK::Individual::toString (   )  const [virtual]

creates a string representing the individual Subclasses must override this method to output an appropriate representation of the Individual. Returns: a string representation of the individual Reimplemented in genetiK::ga::Individual, and genetiK::gp::Individual.
