Detailed Description

The carrier of a genome; can have phenotype.

Another central feature of an Individual is that it's fitness in an EAEnvironment can be measured.

Individual (  const Genome &    prototype )  [explicit]

Member Function Documentation

void addGenesTo (  Genome &    g, const StringMap &    params )  [static]

Passthrough to the Genome of the Individual. Definition at line 65 of file individual.cc. References Selector::addGenesTo(). Referenced by SimplePopulation::SimplePopulation().

void addking (    )  [inline]

Passthrough to the Genome of the Individual. Definition at line 143 of file individual.h. References Genome::addking(). Referenced by EAStrategy::evolve().

void check (    )  [virtual]

Implementation for Object. Definition at line 212 of file individual.cc. References Genome::check().

double equality (  const Individual &    other )  const [inline]

Passthrough to the Genome of the Individual. Definition at line 149 of file individual.h. References Gentainer::equality(), and genome.

double evaluate (  EAEnvironment &    envr, bool    force = false )

Evaluates the fitness of the phenotype in the given environment. The evaluation is done as many times as defined for the environment. The resulting fitness of the evaluations is averaged. The multiple evaluation is useful if the environment or the decoding from genotype to phenotype has randomness. The fitness is also cached for later comparisons, if the genotype does not change. Parameters: envr  Environment to evaluate the fitness in. force  Force re-evaluation of the fitness. Definition at line 103 of file individual.cc. References EAEnvironment::evals(), and EAEnvironment::evaluate(). Referenced by EAStrategy::evolve().

bool execute (  const GeneticMsg &    msg )  const [inline]

Passthrough to the Genome of the Individual. Definition at line 133 of file individual.h. References Gentainer::execute(). Referenced by InterGene::execute().

const Map<String,Object>& features (    )  const [inline]

Returns a reference to the phenotypic features of the Individual. Definition at line 77 of file individual.h.

int getage (    )  const [inline]

Returns the age of the individual; how many generations it has been an elite. Definition at line 108 of file individual.h. Referenced by print().

const Genstruct* getGene (  const GeneticID &    n )  const [inline]

Passthrough to the Genome of the Individual. Definition at line 139 of file individual.h. References Gentainer::getGene(). Referenced by FloatTestEAEnv::evaluateg(), and BinaryTestEAEnv::evaluateg().

int getkings (    )  const [inline]

Passthrough to the Genome of the Individual. Definition at line 145 of file individual.h. References Genome::getkings().

void incarnate (  bool    init )

Resets the individual to birth conditions; removes any phenotypic features. Parameters: init  Giving a TRUE value causes the genome of the individual to be initialized (randomized). Definition at line 69 of file individual.cc. References Gentainer::execute(), and Selector::read(). Referenced by Individual(), pointMutate(), and recombine().

void init (    )  [inline]

Passthrough to the Genome of the Individual. Definition at line 135 of file individual.h. References Genome::init().

DataOStream & operator>> (  DataOStream &    out )  const [virtual]

Implementation for Object. Verbose printout. Definition at line 203 of file individual.cc.

const Object& operator[] (  const String &    key )  const [inline]

Returns a const phenotypic feature. Definition at line 69 of file individual.h.

Object& operator[] (  const String &    key )  [inline]

Returns a phenotypic feature. Definition at line 66 of file individual.h.

bool pointMutate (  const MutationRate &    k )

Passthrough to the Genome of the Individual. Definition at line 157 of file individual.cc. References incarnate(), and Gentainer::pointMutate().

void print (  TextOStream &    out )  const

Brief printout. Definition at line 174 of file individual.cc. References getage(), and Genome::print().

void recombine (  const Individual &    a, const Individual &    b )

Passthrough to the Genome of the Individual. Definition at line 152 of file individual.cc. References genome, incarnate(), and Gentainer::recombine().

void remove (  const String &    key )  [inline]

Remove a phenotypic feature. Definition at line 63 of file individual.h.

const Selector& selector (    )  const [inline]

Returns the selection handler of the Individual. Definition at line 112 of file individual.h. Referenced by SelectionMatrix::calculateMatrix().

void set (  const String &    key, Object *    val )  [inline]

Add or change a phenotypic feature. Definition at line 58 of file individual.h.

void setSelector (  const SelectionPrms &    templ )

Sets the selector of the Individual using the given template. This method is typically called by a Population or it's EAStrategy, and the template consists of global selection parameters. Definition at line 223 of file individual.cc.
