Method Detail

setAssociationManager

public void setAssociationManager(AssociationManager associationManager)

doTrial

public boolean doTrial()

Method to perform trial move.

Specified by:

doTrial in class MCMove

populateList

protected int populateList(AtomArrayList mySmerList)

getChi

public double getChi(double temperature)

Description copied from class: MCMove

Chi is the parameter within standard Metropolis Monte Carlo. The probability of accepting the move is given by min(1,chi).

Specified by:

getChi in class MCMove

Parameters:

temperature - used to compute chi

Returns:

chi

energyChange

public double energyChange()

Specified by:

energyChange in class MCMoveBox

acceptNotify

public void acceptNotify()

Method called by IntegratorMC in the event that the most recent trial is accepted.

Specified by:

acceptNotify in class MCMove

rejectNotify

public void rejectNotify()

Method called by IntegratorMC in the event that the most recent trial move is rejected. This method should cause the system to be restored to the condition before the most recent call to doTrial.

Specified by:

rejectNotify in class MCMove

affectedAtoms

public AtomIterator affectedAtoms()

Specified by:

affectedAtoms in class MCMoveBox

setBox

public void setBox(Box p)

Description copied from class: MCMoveBox

Sets the box on which this move acts. The box itself can be changed via this method, if desired.

Overrides:

setBox in class MCMoveBox

getAtomSource

public AtomSource getAtomSource()

Returns:

Returns the atomSource.

setAtomSource

public void setAtomSource(AtomSource source)

Parameters:

atomSource - The atomSource to set.
