Constructor Detail

DistributedLattice2DLifeSpace

public DistributedLattice2DLifeSpace()

Creates a lifespace. The dimensional parameters are got from Configuration.

DistributedLattice2DLifeSpace

public DistributedLattice2DLifeSpace(int x_size_,
                                     int y_size_)

Creates a lifespace with different with dimension x * y. Setting up the local servers and conects to the remote servers.

Method Detail

injectGenome

public void injectGenome(GeneticCodeTape ct)

Injects the genome into the soup. The target cell is random.

Specified by:

injectGenome in interface LifeSpace

getAllOrganisms

public DigitalOrganismIterator getAllOrganisms()

This method provides all the organisms of the lifespace. This feature is needed when making the update.

Specified by:

getAllOrganisms in interface LifeSpace

getNeighbours

public DigitalOrganismIterator getNeighbours(DigitalOrganism digorg)

This method gives the neighbours of an organism. This is needed when an organism interact with its neighbourhood. Here the topology is 8-neighbourhood on a toroidal two dimensional lattice.

Specified by:

getNeighbours in interface LifeSpace

getOrganismRandomly

public DigitalOrganism getOrganismRandomly()

Gives an organism randomly from the entire 'soup'. It's needed for point mutations for example.

Specified by:

getOrganismRandomly in interface LifeSpace

getSize

public int getSize()

Gives the capacity of the lifespace.

Specified by:

getSize in interface LifeSpace

getRegion

public DigitalOrganismIterator getRegion(double percent)

Description copied from interface: LifeSpace

Returns organisms from a connected local territory in the lifespace. (Should return always a new iterator.)

Specified by:

getRegion in interface LifeSpace

Following copied from interface: physis.core.lifespace.LifeSpace

Parameters:

percentage - The percentage of organisms to be returned.

getSomeOrganisms

public DigitalOrganismIterator getSomeOrganisms(double precent)

Description copied from interface: LifeSpace

Returns some organisms. The organisms should be distributed uniformly in the whole lifespace. (Should return always a new iterator.)

Specified by:

getSomeOrganisms in interface LifeSpace

Following copied from interface: physis.core.lifespace.LifeSpace

Parameters:

percentage - The percentage of organisms to be returned.

getWest

public DigitalOrganism[] getWest()

Specified by:

getWest in interface Remote2DLattice

getEast

public DigitalOrganism[] getEast()

Specified by:

getEast in interface Remote2DLattice

getNorth

public DigitalOrganism[] getNorth()

Specified by:

getNorth in interface Remote2DLattice

getSouth

public DigitalOrganism[] getSouth()

Specified by:

getSouth in interface Remote2DLattice

createSocket

protected java.net.Socket createSocket(java.lang.String host_port)
