Imagine you give me a Rubik's cube and ask me to solve it. I finish it in only 15 seconds and this is what it looks like:

Now, what aspect of solving Rubik's cube would you say I missed?

Re: Anyone know how to adjust the clock width in Arena?

The names are shown below the clock as well. I think those boxes on the left and right are supposed to contain the engines' logos.

Re: Does anyone have a very old AMD machine ?

Thanks Colin, very useful ! So 43 seconds for that Crafty bench at 2.5Ghz. So if that same CPU was running at 2.4Ghz it would probably be 45 secs. And 7,624 ms for SF8, which at 2.4Ghz would be around 7,300 ms. That can't be right. I guess you flipped the 25/24 part of the equation on the last one.

With regex you can do '\bX\b' and it will ignore X's having other letters before or after it. Most editors have an option 'match whole word only', which does the same thing.

Re: PSQT for move ordering ?

I don't know why they should be different. That example with the knight is pretty close to typical values for a normal psqt, I think.

Re: PSQT for move ordering ?

Where can I find them Well, you have to write the code. It's not something you find in a box in the garage. Do you mean what values to use? I use the same tables as in the evaluation function. psq[piecetype][to_sq] - psq[piecetype][from_sq] That's it. I use it only for moves with no history score. ...

Re: Game time in fraction of minutes in Arena.

You should probably use a small time increment to avoid time losses, though. Maybe 100 ms or so.

Re: Game time in fraction of minutes in Arena.

Choose blitz mode. Set initial time to 30 seconds and increment to 0 milliseconds.
