Re: YATT.... (Yet Another Testing Thread)

A. How about showing me a post you wrote, where the primary point was "Bob, the problem with your testing is that you are using only 40 positions (even though many others are using the same positions). How about this one? http://www.talkchess.com/forum/viewtopic.php?t=16675&start=0 :roll: If you wo...

Re: Testing thread summary for the weary

Good summary! :lol: I want to comment on the point where it ascribed to me the statement: "That's probably not the source of dependence." I would agree to that, if you said "the obeserved dependence in Bob's first two runs " This was a very particular kind of dependence, between the games within a r...

Re: Shartranj! and FR

I think this is a problem that has already been solved in the most recent version. The point was that the WB move disambiguation is only aware of the initial castling rights, not of the actual castling rights of the current position, and the move generator was not skeptical enough to test if an actu...

Re: YATT.... (Yet Another Testing Thread)

It now appears that there was a correlation issue, but not one anyone seemed to grasp until Karl came along. ============================================================ can lead to different moves and even different game outcomes. However, we are doing _almost_ the same thing in each repetition, s...

Re: YATT.... (Yet Another Testing Thread)

I suppose you guys are going to keep up with the "stampee feet, error, stampee feet, bug, stampee feet, etc" no matter what happens? Again, completely wrong. As soon as there would be new data relevant to this matter, we would of course refine / reconsider our position. But as you are not providing...

Re: YATT.... (Yet Another Testing Thread)

It now appears that there was a correlation issue, but not one anyone seemed to grasp until Karl came along. This is still absolute bullshit. Karl stated that the results would be farther from the truth when you used fewer positions. But they would have been closer to each other, as they used the s...

Re: YATT.... (Yet Another Testing Thread)

It appears to require a _large_ number of games, measured in the tens of thousands, to measure small changes, assuming it is even possible to do this... My intent with these tests is to attempt to quantify the _minimum_ testing necessary to say whether a change is good or bad... The error in score ...

Re: YATT.... (Yet Another Testing Thread)

So there really is a difference between the 2 sets of starting positions. I think more test with different starting sets would be interesting. The difference is that the data using the first set of starting positions is somehow corrupted, as it seems now, in particular the first run. So averaging t...

Re: Shartranj!

Right, I fixed Dabbaba so it won't freak out when the Shatranj fen starting position is loaded. This a just a workaround i.e it wont accept any other Shatranj position other than the standard starting one.. http://www.mediafire.com/?dzmjjlet17g Jim. OK, our messages crossed. But it is good to have ...

Re: Shartranj!

Ha! I have found a work-around after all. I can tell WinBoard to send a setboard to only one engine. After all: The WinBoard is SMARTER! :lol: The trick is to hide the WB protocol command in the "computer string", as this string can be specified for each engine individually. And, unlike the "init st...
