Coulomb (electrostatic) score between a pair of particles. More...
#include <IMP/atom/CoulombPairScore.h>
Inheritance diagram for IMP::atom::CoulombPairScore:Coulomb (electrostatic) score between a pair of particles.
The two particles in the pair must be Charged particles. The form of the potential is
\[ \frac{1}{4\pi\epsilon_0\epsilon_r} \frac{q_i q_j}{|r_{ij}|} \]
where \(\epsilon_0\) is the permittivity of vacuum, \(\epsilon_r\) the relative dielectric (adjustable; 1.0 by default), \(q_i\) and \(q_j\) the charges on the two particles, and \(|r_{ij}|\) the distance between them.

Overload this method to specify the inputs.
Implements IMP::ParticleInputs.

virtual |
Compute the score and the derivative if needed over a set, only if "good". This functions similarly to evaluate_indexes(), but may terminate the computation early if the total score is higher than max.
Reimplemented from IMP::PairScore.
Definition at line 53 of file CoulombPairScore.h.

virtual |
Compute the score and the derivative if needed.
| m | the model of vt |
| vt | the index in m of an object of type ParticlePair |
| da | a DerivativeAccumulator that weights computed derivatives. If nullptr, derivatives will not be computed. |
Implements IMP::PairScore.
|
virtual |
Compute the score and the derivative if needed over a set.
| m | the model of o |
| o | objects of type ParticlePair, specified by index |
| da | a derivative accumulator that weights computed derivatives. If nullptr, derivatives will not be computed. |
| lower_bound | index of first item in o to evaluate |

virtual |
Compute the change in score and the derivative if needed over a set.
The score for each o[indexes[x]] is updated in score[indexes[x]] and the total difference between the old and new score values (over the set) is returned.

virtual |
Compute the score and the derivative if needed over a set.
Like regular evaluate_indexes(), but the score for each o[x] is also returned as score[x].
