This was the last time that I tested Collosus 2007a, since then it has made a great progress specially versus Movei


I got this result of Colossus 2007a vs Movei403 progress 4 6 10.

Colossus 2007a is a very strong program at Blitz

It may be possible to get even bigger improvement by changing personality but it needs to be tested

comments
1)I still allow the progress personality but I doubt if with hash something different than 0 0 0 will be better.

2)I change some numbers relative to default movei and I forgot to change them back and it is possible that mobilitydivider 64 is not the best
or that you need first to change the knight and bishop square tables to make it works.

3)less_reduce 1 that is in the file that I sent you mean that movei does not reduce pass pawn pushes or extended moves.
It seems to help based on my tests so every personality should include less_reduce 1

4)There are some parameters that by default are 0 that mean not used
specailly:
rook_factor 0
a_weaker 0
extreme_pawn_array 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0history_verification_number 1

It may be possible to get even bigger improvement by changing personality but it needs to be tested

bigger number for rook_factor mean increasing the value of the rook in the endgame
bigger number for a_weaker mean less value for extreme a or h pawn in the opening and more value for them in the endgame

big history_verification number mean less pruning based on history information when 1 means that history information does not prevent pruning.

My result so far with that version are the following results:

1)Movei-Fruit2.0 1+1 55-45
2)Movei-Glaurung1.2.1 3/40 13-11(FRC)
3)Movei-Fruit2.0 5/40 21.5-18.5

Note that it is very dangerous to get conclusion based on small number of games.

In the first match against fruit if you divide the match to 5 matches of 30 games results were as follow:

1)12-8
2)10-10
3)6.5-13.5
4)13.5-6.5
5)13-7

It seems that movei is better than fruit2.0 but
you can see that if you use 20 games(match number 3) or 40 games(match numbers 2-3) you get win for fruit2.0

Even 60 games(matches number 2-4) may give a misleading score of 30-30.
