Go up one level in this thread
Depth new >= depth old is a pretty crappy replacement scheme IMO. You risk filling the hash with worthless nodes. And that will kill MTD(f) as it will mean you have to do the same work repeatedly in the new null window search, and it may harm other search implementations. I actually prefer a repalce always scheme to that one. Better to use a two slot scheme. Probe both slots for a hit. One slot is always replace the other is depth or deeper. If you don't get a hit you replace according to the two schemes. MvH Dan Andersson
