I never understand these nps issues. How can we tell if one program processes less or more nodes per second than another ? For example: _ What says that Fritz is not counting leafs as well ? _ How do we know that Hiarcs is not skipping nodes from quiescence search in its count ? _ Is there any reason why a program should count hash hits or not ? _ Are cutoffs counted or not ? etc. etc. These examples are a bit extreme but I mean that maybe we are just fool to put any faith in the nps given by different engines. What's more it may happen that two versions of a same program change the way nodes are counted, look for example at the last Yace release notes: "Changed the method of counting nodes. Yace will now count less nodes and will show less nodes/s. Actually it is even slightly faster, nevertheless." Souldn't we just say that nps does not mean anything or at least very few ?
