#include <IMP/npc/CompositeRestraint.h>
Inheritance diagram for IMP::npc::CompositeRestraint:Score a set of particles that form a composite.
Similarly to IMP::core::ConnectivityRestraint, this ensures that a set of Particles remains connected, but allows how they are connected to change (for example, A-B-C would score as well as B-A-C). However, unlike that restraint, it acts on Particle type (in the case where there are several distinct Particles of the same type) and allows the stoichiometry to change (For example, A1-B1-C1 would score similarly to A1-B2-C2 or A1-B1-B2-C1).
To use, first create the restraint and then call add_type() for each distinct protein type, e.g. to enforce the composite ABC where there are two copies of protein A and B and a single copy of protein C use: {code} add_type([A1, A2]) add_type([B1, B2]) add_type([C1]) {code}
The restraint scores by computing the complete graph connecting all the particles (where the particles are the vertices and the edges are the value of the PairScore), then calculating the minimum spanning tree, and then using the lowest scoring subgraph that includes at least one of each protein type. This is made much more efficient if the restraint's maximum score is set (set_maximum_score()).

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.
| ParticleIndexPairs IMP::npc::CompositeRestraint::get_connected_pairs | ( | ) | const |
Return the set of pairs which are connected by the restraint.
This set of pairs reflects the current configuration at the time of the get_connected_pairs() call, not the set at the time of the last evaluate() call.
