Uri what is the difference between Movei421 and Movei423 ?

[pichy]

Uri Based on these test I believe that Movei421 is slightly stronger than version 423, what is the main difference between Movei421 and Movei423 ?

[Uri Blass]

one of the difference is fixing bugs in evaluation to have symmetric evaluation.
Another difference is higher score for the part of my mobility score that is similiar to fruit's mobility.

You can change mobilitydivider that is a parameter of version 423
it is practically fixed to be 512 in version 421 and you cannot change it in version 421.

In version 423 it has default value of 128 because I guessed that 128 is better than 512.

It is possible that my guess was wrong and it is better to use 512 and I did not test it with enough games to be sure.

Note that I read in the past an opinion that bigger values of mobility are better at longer time control and I do not know if it is correct.

I think that it may be interesting to test the following personality

The idea is simply to increase mobility score and as compensation have almost constant knight and bishop piece square tables.

result after 8 games against default 423 at 1,000,000 nodes per move is very promising
7-0 and 1 draw for the new personality but I guess that this is mainly because of luck and I plan to play more games.

Uri

[Uri Blass]

As I said you cannot trust 7-0 and 1 draw

result now is only 14-9-12 for the new personality(so the difference got slightly smaller).

[Uri Blass]

Now the result is improving

26-14 with 16 draws for the new personality.

[Uri Blass]

one of the difference is fixing bugs in evaluation to have symmetric evaluation.
Another difference is higher score for the part of my mobility score that is similiar to fruit's mobility.

You can change mobilitydivider that is a parameter of version 423
it is practically fixed to be 512 in version 421 and you cannot change it in version 421.

In version 423 it has default value of 128 because I guessed that 128 is better than 512.

It is possible that my guess was wrong and it is better to use 512 and I did not test it with enough games to be sure.

Note that I read in the past an opinion that bigger values of mobility are better at longer time control and I do not know if it is correct.

Uri

Yes based on these results to use 512 it seems to be better than 128

I think that it may be interesting to test the following personality

The idea is simply to increase mobility score and as compensation have almost constant knight and bishop piece square tables.

result after 8 games against default 423 at 1,000,000 nodes per move is very promising
7-0 and 1 draw for the new personality but I guess that this is mainly because of luck and I plan to play more games.

Uri

Are you saying that I should include the value for the bishop and knight piece square tables, making my new Movei_changes423 configuration settings look like this

candidatefactor 3 progress 10 10 10 0

Yes

candidatefactor 3 progress 10 10 10 0 are not needed but they change nothing because they are the default values of 423.

This setting seem promising also based on my tests.

After 64 games
29-15 with 20 draws against default setting based on my tests with fixed number of nodes.
Of course more games are needed.

bigpositional_opening and bigpositional_endgame are the minimal positional advantage(in centi-pawns) that is needed to give additional bonus for big positional advantage.

I increased the positional score so it is logical to reduce that bonus and have it in less cases.
I am not sure if 135 135 is the best and maybe bigger numbers that I did not try are even better.

Uri

A small change is really making a difference, simply take a look at mighty Alaric704 and Wildcat7.0 behind both version of Movei423 and 421, but the main difference now is that Movei423 is scoring better than Movei421

PS: I left it with mobilitydivider 512 instead of 64 and I am getting good results so far
