Eval tuning I strictly do at fixed depth. I don't want external factors like time control or permanent brain to interfere. Enough volume will flatten all the horizon effects eventually, both sides.

running in a GUI like Arena has even more drawbacks, I'd suggest a command line tournament manager like cutechess-cli and run on time.

I like Arena because it supports nodes-matches. IMO a better way to test search related changes than on time.

BTW your C is very assemblish, lovely stuff, really, no joking: it has a kind of vintage fashion.

All my engines were in assembler. I just can't get used to these brackets.

Code:

{ 
   {
       {
           {
           }
       }
   }
}

Things like that drives me crazy Wink


Hi Ed,

In itself running fixed depth matches is not a bad idea. However it tunes a lot better if you get through tactical barrier. That barrier is far above 8 ply.

Just go tune at something like 1 minute entire game and 0.1 second increment.

The idea is that after an engine gets 'better' and more 'well tuned' that you also start to search deeper because of the improvements, which scales up th experiment.

Soon you'll move to 5 minutes a game and so on.

If your engine is capable of running as a winboard engine you'll need to use other tools. Most Gui's simply aren't stable enough to play that many games nor fast enough, as they need to update the graphics and do all sort of central locked i/o.

A core or 30 is no luxury to do stuff like this.

Don't believe by the way that just playing games is the holy grail, they do more than just play games for parameter tuning.

Vincent
