G4VImportanceAlgorithm is an interface used by importance sampling to get the number of copies and weight a mother particle should be split into when crossing a boundary of "importance cells". The interface defines the input to be the ratio of the pre over the post importance and the weight of the mother track. It returns a struct containing the number of copies (including the mother track) to be produced and the weight of each track. A user defined algorithm deriving from this interface may be used by the importance sampling. More...
