If it has a full width-search, isn't this a contradiction ? shouldn't it be vice versa ? >It's my belief also that it's wise to construct your program such >that it is guaranteed to improve with time and depth, and that >there should be no problem it could not eventually solve (although it As I said, I believe also that genius has a kind of shifting the search by trying to find out if there are better moves than the 1,3,5,7,9 moves in the main-line. It has first a pessimistical main-line and later it tries to exchange the pessimistic 1,3,5,7,9 moves with other moves. So asymmetrie is not all. There are a few other different weird ideas in genius. >could take billions of years with current hardware.)
