dear Marco
is it possible that you increase the items in the Setting that can be changed with the items that could be changed in stockfish till April 2014 especially additionelly to contemt
mobility midgame, passed pawn endgame, space, aggressiveness, cowardice, emergency base time, emergency move time, slow mover to create an sugar with aggressive stile.
No matter when elo goes down 50 elo but very interresting games are the result with the aggressive Setting against minimal weaker engines.

I'm already working on a version MZ that will include the old parameters
please just be patient, and a secondary priority at this time
but I want to devote proper attention to elo can lose less than recent versions
We will definitely a regression as a compromise, this I can anticipate it to you with confidence

Marco - how many additions have you made to the Stockfish coding aside from just changes to existing parameters?

Is there anywhere that you list everything that you've done?

Just wondering.

Graham.

Hi Graham

Additions and Deletions are listed with each release
changes to existing parameters obviously lead to assessments of the positions
and the search algorithm different, due to the influence of the tuning of the weights and applied bonus
However, and can control the differences by making a comparison with the official version of the code using Notepad ++

Marco

Hi Marco
Can you suggest which Parameters of the Setting i should Change to create something like an aggressive Version of sugar 5.1 and to which degree and worth i should Change the suggested items
Thanks

At the moment there are no parameters in the code that you can tune to influence the style of play, and the old code strings should be reviewed as they are because they are incompatible.
we will see in the future.

This is based on my old InstaMove idea but with two significant impro…
…vements.

1) Added much better instability detection inside the search itself.
2) When it's time to make a FastMove we no longer make it instantly but still
spend at least 10% of normal time verifying it.

Hi.
Can most of the setting values in sugar be unchanged to have good game?
Or have the settings to be changed?
Thank you very much for your answer.
