Detailed Description

Class to minimize conformation changes for random moves.

Very experimental !!!

Only used within ZScatterer.

Definition at line 168 of file ZScatterer.h.

Member Function Documentation

REAL ObjCryst::ZMoveMinimizer::GetLogLikelihood ( ) const
virtual

Get -log(likelihood) of the current configuration for the object.

By default (no likelihood evaluation available), this is equal to 0.

This call should not be recursive, it is the task of the algorithm to get the sum of likelihoods for all objects invlolved.

Note
contrary to the old "Cost Function" approach, with log(Likelihood) there is no 'choice' of cost function, so that it is the task of the object to give the optimized likelihood (possibly with user options).

Reimplemented from ObjCryst::RefinableObj.
