Hello,
Thanks to a few people on here for testing out Exacto 0.e. While it shares the same name as my last program, Exacto 0.d, this new version is really a brand new version. Is there anything I need to do to get the new version onto the CCRL?
Anyway, here's the website. It contains a list of the features:
http://math.berkeley.edu/~sparks/exacto/
The source code is included and covered under a BSD type license (but use it at your own risk - I am neither a chess player nor a programmer). The engine is meant to use with WinBoard/XBoard/Arena.
Best,
Dan

Re: Engine release Exacto 0.e
Could you give us a rough idea of some engines that you feel are around the same strength?Exacto wrote:Hello,

You do not have to do anything. I will test it for the 40/4 list.Exacto wrote:Is there anything I need to do to get the new version onto the CCRL?

you may easily quarter your plain magic tables sizes, i.e. 2MB instead of 8MB for rooks, if you allow constructive index collisions, where redundant outer one-bits of the occupancy may share the same attack set and entry.

Code: Select all
if(rook_moves[square][quickhash(x, magic, bits)] == all_set){
// A new hash entry
rook_moves[square][quickhash(x, magic, bits)] = y;
} else if(rook_moves[square][quickhash(x, magic, bits)] != y) {
// A bad collision

Re: Engine release Exacto 0.e
Thanks guys!
- The engines I test against are usually Clarabit, Firefly, Joker, Adam, Neurosis, and a few others between 2200-2330 on CCRL. I estimate the rating for Exacto 0.e should be higher than 2100, but lower than 2200. (Compared to the CCRL ratings.)
- This version is supposed to be called 0.e. I guess I didn't put that in the title of the executable, but it does say which version it is when you boot it up.
[EDIT: Oh! You probably mean like... 1.0 instead of something so consecutive... yeah, that might have been a good call.]
- It doesn't work on XP at the moment, which is something I plan to address in the next version. Unfortunately, the program searches different game trees when compiled in GCC vs Microsoft, but if I can sort that out, I'll compile in Mingw-w32 for people on XP.
- As far as my magics - good eye catching that. Yes, I allow constructive collisions. But, for whatever reason, my code wasn't able to generate magics for smaller tables. It would just sit their looping seemingly indefinitely (20-30 minutes, until I closed it and decided to just use 14/11 bit magics).

I guess your randoms are not sparse enough. See this proposal by Tord Romstad:Exacto wrote: - As far as my magics - good eye catching that. Yes, I allow constructive collisions.

uint64 random_uint64() {
uint64 u1, u2, u3, u4;
u1 = (uint64)(random()) & 0xFFFF; u2 = (uint64)(random()) & 0xFFFF;
u3 = (uint64)(random()) & 0xFFFF; u4 = (uint64)(random()) & 0xFFFF;
return u1 | (u2 << 16) | (u3 << 32) | (u4 << 48);
}
uint64 random_uint64_fewbits() {
return random_uint64() & random_uint64() & random_uint64();
}

Re: Engine release Exacto 0.e
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.]

Re: Engine release Exacto 0.e
Exacto 0.ex-win32 crashed under Arena 3.5 and WinBoard 4.7.3a with an identical diagnostic error by Windows:
error in application-the command in 0x7c939f07" refers to storage in "0x00000fa0"- the application "read" could not be executed from the storage-click on "ok" to finish the program
(annotation: text was originally in German because I use XP SP3-32 Bit
Deutsche Edition)
A complete new installation of Arena / WinBoard did not solve this problem.
Arena ~ http://www.playwitharena.com/?Download
WinBoard ~ http://www.open-aurec.com/wbforum/viewt ... 19&t=51528
Any similar experiences of Windows XP 32-bit users?
