Re: Pawn structure tuning

If I can ask, how do you compare the 10 depth search eval from Ethereal with its static evaluation? The two evals can differ a lot. The goal, which may or may not be founded, is to adjust positions where the search() differs greatly from the eval(). Namely, imagine a position where we have taken a ...

Re: Pawn structure tuning

I would stray from trying a full array setup. I always prefer the minimal approach. If a full array passes testing in the same number of games as only adding an additional dimension for X, you clearly prefer the simpler approach. The limited data is of course prohibitive, but I also feel a sort of a...

Re: Suggestion to CCRL

This would be a hack, but here goes. It seems engine that are 64-bit have "64-bit" in their name, the ones that are 32-bit have either nothing, or 32-bit. Leave everything as it is. Then add a Javascript procedure to the top of each page, which would add "32-bit" to any engine that doesn't already ...

Re: Official Release of Ethereal 12.00

Can you confirm that the engine is still running? IE the binary still shows up in your task manager, despite not reporting the best move to the GUI? When I compile Ethereal on Linux, everything seems fine. But when I run your *exe files on Wine, I get this: wine Ethereal12.00-x64-pext.exe 000b:fixm...

Re: Official Release of Ethereal 12.00

I'm sorry to ask where I can find engine versions Ethereal 12.01. If you are able to compile source, you can get the latest source from here : https://github.com/AndyGrant/Ethereal Otherwise, I could compile binaries for you and upload them somewhere for you to grab. Whichever works for you. Andrew

Re: Removing Large Arrays

The new code is an abomination {to me, which means little}. Stockfish is so crammed with magic numbers that it should be a Disney movie with wands and sorcerer's apprentices and bippity-boppity-boos. My only point was that a 20 line program to compare the two methods is not valid. You have to profi...

Re: Removing Large Arrays

I've long disagreed with a certain users string of "simplifications". Is an array of 64 values a bit big and bulky? Yes. But any adult can view that array and identify the trend in the values. I would keep that array, because its very clear to the reader what is being done. Now, you have to have far...

Re: Official Release of Ethereal 12.00

I think what people are trying to point out here is that the log doesn't show a 'bestmove' command from the engine in reply to 'stop'. Failing to send the 'bestmove;'' would be a violation of the UCI specs, and it is quite conceivable that some GUIs would hang forever while waiting for it. Any prog...
