Detailed Description

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

Note
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).

The ensure proper evaluation, the ScoringFunction is divided into a number of sub scoring functions, one per possibly moved particles. Each of

Constructor & Destructor Documentation

IMP::core::IncrementalScoringFunction::IncrementalScoringFunction ( const ParticlesTemp &  to_move,
const RestraintsTemp &  rs,
double  weight = 1.0,
double  max = NO_MAX,
std::string  name = "IncrementalScoringFunction%1%" 
)

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

Parameters
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.

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

Return a set of restraints equivalent to this scoring function.

Implements IMP::kernel::ScoringFunction.

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

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::kernel::ScoringFunction.

ScoreStatesTemp IMP::core::IncrementalScoringFunction::get_required_score_states ( ) const
virtual

Return any score states needed in order to do scoring.

Implements IMP::kernel::ScoringFunction.

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.
