Inheritance diagram for IMP::core::IncrementalScoringFunction: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.
To ensure proper evaluation, the ScoringFunction is divided into a number of sub scoring functions, one for each possibly moved particle.

Pass the particles that will be individually moved, and the list of restraints to evaluate on them.
| to_move | particles to be moved, must contain at least one particle |
| rs | restraints (can be empty in principle, in which case the score is 0) |
| weight | the weight used to scale the restraints |
| max | maximum value for evaluate_if_good or evaluate_if_below, can be ignored for most purposes |
| name | The name template to use for the scoring function. |

| 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 |
Return a set of restraints equivalent to this scoring function.
Implements IMP::ScoringFunction.
|
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::ScoringFunction.
|
virtual |
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 |
Get information about the module and version of the object.

virtual |
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.
