Subject: Using just Upperbounds and Lowerbounds

Author: Alvaro Jose Povoa Cardoso

Date: 11:19:25 02/01/01

Does any one tried to use just Upperbounds and Lowerbounds in hashing, ignoring
ExactScore entries?
My question has to do with the fact that if we use ExactScores we don´t get long
PVs to feed in the next iteration, even if we extend PVs from hash.
My testing shows that if we do not use ExactScore entries in the hash table, we
end up with very long PVs that can be fed into the next iteration in order to
aproximate the minimal tree. After all, ExactScores are rare compared to
Upperbounds and Lowerbounds.

Can someone comment on this?

Thank you
Alvaro Cardoso
