ShellIM

public ShellIM(InteractionModel im)

Method Detail

evaluate

public double[] evaluate(Genotype[] inds)

Description copied from interface: InteractionModel

Evaluates these individuals using the deployment and experiments and procedure of this model.

Specified by:

evaluate in interface InteractionModel

Following copied from interface: jaga.control.InteractionModel

Returns:

an array of the fitnesses of the individuals.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getMaxFitness

public Genotype getMaxFitness()

Specified by:

getMaxFitness in interface InteractionModel

Returns:

The maximum fitness a genotype can achieve. ie. when evolution will stop

evaluationsPerGeneration

public int evaluationsPerGeneration()

Specified by:

evaluationsPerGeneration in interface InteractionModel

Returns:

the number of evaluations per generation to be performed

getNextIndividuals

public Genotype[] getNextIndividuals()

Picks a number of individuals to be evaluated next. These individuals can be from any of the populations as long as there is a standard interface between the caller and this method implementation as to where each come from. Example: may be first element a pac-man, and five others all ghosts..

Specified by:

getNextIndividuals in interface InteractionModel

evaluateNext

public double[] evaluateNext()

Should be same as calling evaluate( pickIndividuals() );

Specified by:

evaluateNext in interface InteractionModel

Returns:

an array of the fitnesses of the individuals.

evolve

public void evolve()

Evolves to the next generation of all/some of the populations involved.

Specified by:

evolve in interface InteractionModel

getNumEvolvers

public int getNumEvolvers()

Specified by:

getNumEvolvers in interface InteractionModel

Returns:

the number of evolvers (ie. populations) acting in this model.

pickIndividuals

public Genotype[] pickIndividuals()

Specified by:

pickIndividuals in interface InteractionModel

Returns:

randomly picked individuals from the evolvers.

getPopulations

public Population[] getPopulations()

Specified by:

getPopulations in interface InteractionModel

Returns:

the current populations of the evolvers.

setPopulations

public void setPopulations(Population[] pops)

Sets the populations of the evolvers to be these

Specified by:

setPopulations in interface InteractionModel

getSnapshotPainter

public islandev.SnapshotPainter getSnapshotPainter()

Specified by:

getSnapshotPainter in interface InteractionModel

Returns:

String displaying performance of fittest individual.
