Engine release Exacto 0.e

[Exacto]

Out of curiosity, what is a typical period to wait for an engine to show up on the CCRL?

Out of curiosity, what is a typical period to wait for an engine to show up on the CCRL?

It's still on my "to do" list for the 40/40 list, along with another three or four engines. Probably a couple of weeks away before testing - I'll let you know when I start.
Charles, Shaun and Brent are testing other engines currently as well.

As for 40/4, Gabor is currently away and Adam is doing some Gaviota testing for Miguel, so there probably won't be an update of this list this weekend.
Not sure as to what other 40/4 testers are currently doing.
Probably a couple of weeks away here as well.

Cheers,
Graham.

Sorry. I have not been able to test it because my only Windows computer uses XP 64bit, and Gabor is away from home and not doing any testing this week.

I am about to start a tournament for the engine but I have a problem. Under WinBoard I myself can play against it all right but in an engine match it refuses to make a move and "Waiting for engine to start" is displayed. Then the game is interrupted, another one is started, the opening book moves are made and again "waiting".

Some hint would be appreciated.

I used the wb2uci adapters. I also had to replace the book.bin file with a 0kb book.bin file.

Ruxy - following up on the XP issue. I've made a separate set of compiles for XP (32 bit) and Macintosh (64 bit) platforms through GCC. An important note: in order to switch into GCC I had to track down and squash a bug, which means that this version may search slightly different trees than 0.e. On my website (link above) it is listed as 0.e.x.

But, 0.e.x is not a "release," rather, it's just something for people on XP32 / Mac to be able to play against my engine. So, if testing, please test 0.e on Win64.

[Future versions should be distributed with identical XP32(GCC)/Win64(MS)/Mac64(GCC) compiles.]

It seems that in the distributed code no Bitscan to 32 bits.

Code: Select all

inline
uint8_t bitscan(uint64_t bb) {
	#ifdef __GNUC__
		return __builtin_ctzll(bb);
	#endif
	#ifdef _MSC_VER
		unsigned long index;
		_BitScanForward64(&index, bb);
		return (uint8_t)index;
	#endif
}

Code compiles fine with Intel and Visual C **, I can make some compilations.

There is what looks like an error o warning in King Safety:

subscript out of range :
uint8_t const adjacent_files[8]
Write: 64

Code: Select all

#ifdef _KING_SAFETY
		
			if(((adjacent_files[64] ..................
				
			if(((adjacent_files[64] ..............
#endif

A compilation with Visual C + + 2013, XP support (according to Microsoft)8-)

If it works, use the original executable of the author,
No improve.

subscript out of range :
uint8_t const adjacent_files[8]
Write: 64

This is extremely embarrassing! I thought I had fixed this before release. I've since fixed this, but surprisingly 0.e seems to run fine for me and play reasonable chess (!).

It seems that in the distributed code no Bitscan to 32 bits.

I've since added some poor 32 bitscan routines in case people want to compile in Microsoft for 32 bits. But, at the time that I was writing 0.e, my plan was to compile for Win32 through Mingw, where the GCC builtin's still work.

I am about to start a tournament for the engine but I have a problem. Under WinBoard I myself can play against it all right but in an engine match it refuses to make a move and "Waiting for engine to start" is displayed.

Gabor - did Graham's suggestion work? I'm sorry that such measures have to be taken to get my program to work.

As far as the force twice thing, all that happens when Exacto receives "force" is it toggles a bool into and out of force mode. If it happened twice, and it was out of force mode, and then it received a move for white when Winboard expected it to be in force mode, it could in principle respond by moving for black. But, the numbering is throwing me off as well: it says 1... Nf6 in it's thinking output, as if it's responding to 1. d4? I'll have to run through all those commands that Winboard is sending Exacto one by one and see if I can reproduce this in the command line. Thanks!

That is wrong. "force" should put you in force mode. Never out of it. I don't know if there are situations where WinBoard (or other WB-protocol-supporting GUIs) would send redundant force commands, but if they don't it is only by luck that your engine would work.

No problem here playing w/wo book as W/B, but I used the special XP 32bit compile from Mr. Velasco and just match mode.
I noticed from your first debug though that Exacto is already started first in the beginning and then unloaded and started again for your tournament.
Maybe it does not unload correctly and is running twice when the real game starts?
