摘要：
We show that, under appropriate conditions, one can create a hybrid between two given iterations which can perform better than either of the original ones. This fact provides a freedom of choice. We also give numerical examples in which we compare our hybrid with the dedicated Lee-Seung iteration. (C) 2013 Elsevier Inc. All rights reserved.
