Detailed Description

A base class for classes which perturb particles.

Mover objects propose a move, which can then be either accepted or rejected based on some criteria. Most commonly this is a Monte Carlo evaluation scheme.

All changed attributes should be optimizable; it is undefined behavior to try to optimize an attribute which is not.

The output particles (ModelObject::do_get_outputs()) are assumed to be equal to the inputs (ModelObject::do_get_inputs()).

Member Function Documentation

void IMP::core::MonteCarloMover::accept ( )

Accept/commit any changes made to the Particles.

Definition at line 77 of file MonteCarloMover.h.

virtual void IMP::core::MonteCarloMover::do_accept ( )

protectedvirtual

Implement accept_proposed_move(); default implementation is empty.

Reimplemented in IMP::core::SubsetMover, and IMP::core::SerialMover.

Definition at line 102 of file MonteCarloMover.h.

virtual ModelObjectsTemp IMP::core::MonteCarloMover::do_get_outputs ( ) const

protectedvirtual

Get any Particle, Container or other ModelObjects changed by this during evaluation. This is only useful for ScoreStates, at the moment.

Implements IMP::ModelObject.

Definition at line 104 of file MonteCarloMover.h.

Here is the call graph for this function:

virtual MonteCarloMoverResult IMP::core::MonteCarloMover::do_propose ( )

protectedpure virtual

virtual void IMP::core::MonteCarloMover::do_reject ( )

protectedpure virtual

MonteCarloMoverResult IMP::core::MonteCarloMover::propose ( )

Propose a modification.

The method should return the list of all particles that were actually moved and the ratio between the backward move probability and the forward move probability (for Metropolis-Hastings moves). Just return 1.0 for this value if you are not sure.

Definition at line 56 of file MonteCarloMover.h.

Here is the call graph for this function:

void IMP::core::MonteCarloMover::reject ( )

Roll back any changes made to the Particles.

Definition at line 69 of file MonteCarloMover.h.
