|
//
|
|
// This is a base class for an algorithm used for
|
|
// weight window importance sampling. It calculates
|
|
// the new weight of particles and the number of copies
|
|
// it should be split into according to the initial weight
|
|
// of the track and the importance of the cell. The window
|
|
// is defined by the values of Upper and Lower.
