Method Detail

main

public static void main(java.lang.String[] args)

usage

private static void usage()

getTaskLibrary

public TaskLibrary getTaskLibrary()

Returns the tasklibrary.

Specified by:

getTaskLibrary in interface Environment

setLifeSpace

public void setLifeSpace(LifeSpace lifespace_)

Specified by:

setLifeSpace in interface Environment

getLifeSpace

public LifeSpace getLifeSpace()

Specified by:

getLifeSpace in interface Environment

interactionOccured

public void interactionOccured(InteractionEvent ie)

Description copied from interface: InteractionEventListener

Performed when an organism interacts with its environment.

Specified by:

interactionOccured in interface InteractionEventListener

proliferationPerformed

public void proliferationPerformed(ProliferationEvent pe)

Description copied from interface: ProliferationEventListener

When a digital organism divides the new organism must be placed somewhere in the lifespace and the old organism's effective length should be recalculated. The parent organism's VM should be reset. The parent orgainsm should be set fertile. These should be handled in this method by the implementor classes.

Specified by:

proliferationPerformed in interface ProliferationEventListener

getInputData

public int getInputData()

This provides the input from the environment (~food).

Specified by:

getInputData in interface Environment

rotateForward

public void rotateForward(DigitalOrganism digorg)

Rotates the organism's facing forward.

Specified by:

rotateForward in interface Environment

copyShouldBeMutated

public boolean copyShouldBeMutated()

Answers the question: Should the current copied instruction be mutated?

Specified by:

copyShouldBeMutated in interface Environment

divideShouldBeMutated

public boolean divideShouldBeMutated()

Answers the question: Should the current divided codetape be mutated?

Specified by:

divideShouldBeMutated in interface Environment

shouldBeInserted

public boolean shouldBeInserted()

Answers the question: Should the current divided codetape be inserted extra instructions?

Specified by:

shouldBeInserted in interface Environment

shouldBeDeleted

public boolean shouldBeDeleted()

Answers the question: Should the current divided codetape be deleted one instruction?

Specified by:

shouldBeDeleted in interface Environment

getNeighbourRandomly

public DigitalOrganism getNeighbourRandomly(DigitalOrganism digorg)

Description copied from interface: Environment

Returns one organism of the neighbours of the organism specified by the parameter.

Specified by:

getNeighbourRandomly in interface Environment

getRandom

public java.util.Random getRandom()

Description copied from interface: Environment

The only one random-generator in one Physis-instance should be in the environment. There shouldn't be more than one, otherwise accurate experiment repeat would be impossible.

Specified by:

getRandom in interface Environment
