Detailed Description

Score the model efficiently when a small number of particles are changed.

This is a scoring function that computes the score efficiently when a small number of particles are changed.

At the moment moves of one particle at a time are handled most efficiently.
Only full evaluation is supported and information about restraint sets and such are lost (and so one can't count on information about whether the score is good).

To ensure proper evaluation, the ScoringFunction is divided into a number of sub scoring functions, one for each possibly moved particle.

Constructor & Destructor Documentation

IMP::core::IncrementalScoringFunction::IncrementalScoringFunction ( Model m,
const ParticleIndexes to_move,
const RestraintsTemp rs,
double  weight = 1.0,
double  max = NO_MAX,
std::string  name = "IncrementalScoringFunction%1%" 


Pass the particles that will be individually moved, and the list of restraints to evaluate on them.

mModel object containing all particles to be moved
to_moveparticles to be moved; must contain at least one particle
rsrestraints (can be empty in principle, in which case the score is 0)
weightthe weight used to scale the restraints
maxmaximum value for evaluate_if_good or evaluate_if_below; can be ignored for most purposes
nameThe name template to use for the scoring function.

Member Function Documentation

void IMP::core::IncrementalScoringFunction::add_close_pair_score ( PairScore ps,
double  distance,
const ParticlesTemp particles,
const PairPredicates filters 

Close pairs scores can be handled separately for efficiency, to do that, add a pair score here to act on the list of particles.

virtual Restraints IMP::core::IncrementalScoringFunction::create_restraints ( ) const

Return a set of restraints equivalent to this scoring function.

Implements IMP::ScoringFunction.

void IMP::core::IncrementalScoringFunction::do_add_score_and_derivatives ( IMP::ScoreAccumulator  sa,
const ScoreStatesTemp ss 

Do the actual work of computing the score and (optional) derivatives. The list of all score states that must be updated is passed.

Implements IMP::ScoringFunction.

virtual ModelObjectsTemp IMP::core::IncrementalScoringFunction::do_get_inputs ( ) const

Get any Particle, Container or other ModelObjects read by this during evaluation. If you read everything in a container, you can just return that container.

Implements IMP::ModelObject.

virtual ::IMP::VersionInfo IMP::core::IncrementalScoringFunction::get_version_info ( ) const

Get information about the module and version of the object.

Reimplemented from IMP::Object.

Definition at line 121 of file IncrementalScoringFunction.h.

virtual void IMP::core::IncrementalScoringFunction::handle_set_has_required_score_states ( bool  )

Called when set_has_required_score_states() is called.

Reimplemented from IMP::ModelObject.

void IMP::core::IncrementalScoringFunction::reset_moved_particles ( )

Undo the last moved particles.

This is similar in effect to, but perhaps more efficient than, calling set_moved_particles() a second time with the same list.

void IMP::core::IncrementalScoringFunction::set_moved_particles ( const ParticleIndexes p)

Set which particles have moved since the last evaluate.
