Method Detail

init

protected void init()

doTrial

public boolean doTrial()

Description copied from class: MCMove

Method to perform trial move. Returns false if the trial could not be attempted, for example if there were no molecules in the box and the trial is designed to displace an atom; returns true otherwise.

Specified by:

doTrial in class MCMove

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

acceptNotify

public void acceptNotify()

Description copied from class: MCMove

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

Specified by:

acceptNotify in class MCMove

rejectNotify

public void rejectNotify()

Description copied from class: MCMove

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

energyChange

public double energyChange()

Specified by:

energyChange in class MCMoveBox
