Subject: MTD(f)

hi,

i just implemented an MTD(f) search for my checkers program instead of my usual
PVS/NegaScout - it seems to be about same good. in my hashtable i only store the
value and valuetype, and i noticed that in aske plaat's MTD(f) description he
stores both upper and lower bounds in the hashtable. i couldn't figure out a
reason to do this - can somebody enlighten me? i tried in vain to construct some
sequence of null-window calls which MTD(f) might do where it would be of use to
save both bounds, but maybe i'm just missing something simple here?!

cheers
  martin
