etomica.integrator.mcmove.MCMoveInsertDeleteVacancy

All Implemented Interfaces:

IListener

public class MCMoveInsertDeleteVacancy
extends MCMoveInsertDeleteBiased
implements IListener

Looks for atoms without a full set of first nearest neighbors and attempts insertions adjacent to one of those atoms. Hoops are jumped through to ensure detailed balance. Neighbor lists are used to find insertion points and candidates for deletion. Internal lists are constructed (relatively expensive) and then reconstructed when a move is accepted or when some other part of the simulation moves atoms (this part is somewhat hardcoded; enjoy).
