Question about node type in a PVS search

Post by mathmoi » Thu Feb 11, 2010 1:52 am

Hi,

I have a simple question. In a PVS search, in a PV node, if one of the children after the first fail high, I have to search it again with a non-null window. When I do this research, is this node a PV node?

Thanks,

MP

Yes. Any node with non-zero window is a pv node.
