Detailed Description

IndividualFactory: GP-ST-specific IndividualFactory.

This class extends the genetiK::gp::Individual class. It represents an individual as a typed gene tree.

Member Function Documentation

genetiK::Individual* genetiK::gp::st::IndividualFactory::generate (   )  [pure virtual]

abstract generate function This function must be extended by sublcasses to generate appropriate individuals. Returns: a new Individual Implements genetiK::gp::IndividualFactory.

gp::Gene * genetiK::gp::st::IndividualFactory::generateBranch (  unsigned char  height, ETreeInitialization  treeInitialization )  [virtual]

generate a new branch This function generate a new branch. Parameters: height  the max height of the new branch treeInitialization  GROW or FULL Returns: the new branch Reimplemented from genetiK::gp::IndividualFactory.

void genetiK::gp::st::IndividualFactory::generateChildren (  gp::Gene *  branchRoot, unsigned char  height )  [protected, virtual]

populate a node generating all its subbranches This method generates all branchRoot subbranches. Parameters: branchRoot  the gene to be populated height  the max height of the subbranches Reimplemented from genetiK::gp::IndividualFactory.

virtual gp::Gene* genetiK::gp::st::IndividualFactory::generateGene (  EGenerateGeneFlags  flags  )  [protected, pure virtual]

abstract generate gene function This function must be extended by sublcasses to generate appropriate gene. This function returns a random gene obeying the rules specified in flags and the nextGeneType returning a new random gene of type getNextType(). If the new created gene doesn't satisfy the specified rules, an Exception will be thrown Parameters: flags  TERMINAL for a gene with arity equal to 1 and FUNCTION for a gene with greter or equal to 1. If both the flags are specified, you should return a random gene (TERMINAL or FUNCTION) Returns: a random gene See also: getNextType();

gp::Gene * genetiK::gp::st::IndividualFactory::generateTree (   )  [protected, virtual]

generate a new tree It simply calls the generateBranch with the appropriate height and root type. Returns: the new tree See also: generateBranch Reimplemented from genetiK::gp::IndividualFactory.

GeneType genetiK::gp::st::IndividualFactory::getNextType (   )  const [inline]

return the type of the next gene to be created Specifies the type of the next gene to be created. Returns: the type of the next gene See also: generateGene(EGenerateGeneFlags flags)

void genetiK::gp::st::IndividualFactory::setNextType (  const GeneType  nextGeneType  )  [inline]

set the type of the next gene to be created Specifies the next type of the gene to be created. Parameters: nextGeneType  the type of the next gene See also: generateGene(EGenerateGeneFlags flags)
