AnnealingUtility Acts::AdaptiveMultiVertexFitter::Config::annealingTool

Annealing tool used for a thermodynamic annealing scheme for the track weight factors in such a way that with high temperature values (at the beginning) only a slight preference is given to tracks compatible with the estimated vertex position.

With lower temperatures the weighting get stricter such that all incompatible tracks will be dropped at the end while keeping all compatible tracks with a weight=1. Ref.
