Subject: MTD(f) Problems

Author: Oren Avraham

Date: 15:51:20 04/10/02

I've Implemented MTD(f) but it behaives starangely:
only the Alpha Beta returns about -400
white MTD(f) returns in it's first iteration -80
and in the second one the same result (-80)
consequently the search is stopped due to lowerbound >= upperbound condition.
what can cause this bug ? (also when TT is off)
did anyone see something familiar before ?

thank you in advance, Oren Avraham.
