Many thanks John -- that was a fast response! I have some comments in line: >According to my documents, here are the min and max values for the GUI: > >All pieces are between 0 and 15 >Attacker/Defender: -100 to 100 >Strength of Play: 0 to 100 >Randomness of Play: 0 to 100 >Book Depth: 0 to 100 (although no book is deeper than 40 plies) >Search Depth: 1 to 99 (although The King has a max search depth of 46 plies) >Selective Search: 1 to 16 >Contempt for Draw: -5 to 5 >Transposition Table: 512K to 2GB >Material/Positional: -100 to 100 >Control of Center, Mobility, King Safety, Passed Pawns and Pawn Weakness are all >0 to 200 >However, many of these values are translated from what the user sees into the >appropriate values for The King. I'm pretty sure that the material value that is >sent to the engine is in the form of a PERCENTAGE of the typical value. This is >why the default is 100 for pieces. So, a value of 15 for queens (the max) should >result in something like 166 to The King. > >BUT, the Material/Positional value will further modify the values for the >pieces. The more that this value is set towards Material, the higher the piece >values will be, and vice versa. OK, that last part explains it. I was wondering why the The King was not taking any Material/Positional parameter. It also explains why, when I made a MAX personality (all values maxed out), that the Queen was only set to 99 (talking about what the King sees, not the GUI). Had I put the Material/Positional slider the other way, this number would've jumped. Did Johan ever "publish" or let you know of known ranges (perhaps there aren't any) for the King's params? I'm not sure if the GUI was written to constrain the ranges to what was considered "reasonable" or if it was reflective of hard limits? Thanks, Brian
