This is a harmless oversight. I'll add the code, although it really has little effect on things, since the history scores are dragged back toward zero after each move. 4 book moves and these values end up at zero anyway. >2) last_search_value was used in TimeCheck(). > But it is updated at the end of Iteration(), not after each iteration loop. > So last_search_value doesn't contain updated value in TimeCheck(). This is a messy part of the code... I have been working on this every night, as it is too complicated... this happened when Mike Byrne and I were doing some cute time allocation stuff a couple of years ago. It will be "sane" in the next version (I hope). > >Thanks.
