Bundle an open source uci engine with all releases. #311

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Look into bundling Toga with all releases, an open source chess engine.
This was Fredricko's suggestion in another issue.

Perhaps it would be easier to maintain a "chess engine wizard" which downloads 
the
appropriate Toga installer, allows the user to run the installer, and after
installation the user can specify where the engine was installed, what 
parameters to
run it with, etc.

Comming soon. It is looking like there might be different open source engines 
bundled with different installs.

Wouldn't this sort of defeat the purpose of adding in your own UCI engines?  
Why not
let the user define where the UCI engine is located (as is the case now in 
v.93) and
leave it at that, instead of dealing with the headaches of adding in different
engines for different platforms?

fjgrafe: Maybe this is a bug in Raptor w/ how it handles UCI engines? You need 
to do
"ucinewgame", position fen <fenstring> moves <moves in UCI long algebraic> -- 
then
"go infinite" (and if the UCI engine supports it, UCI_AnalyseMode must be 
turned on.

The problem is many users have no idea what a UCI engine is.

I want to bundle one with each release so its just preconfigured and easy to 
use. If
they want to add other ones they can. Raptor even lets you pick the one to use 
when
you turn analysis on.

Also its not a bug there is a place to add the "go command string". Look in the
engine properties. You can even bring them up when analysis is on.

It is a fruit/togaII bug imho. They should support go infinite its part of the 
UCI spec.

I see, well, you should then try to use Stockfish instead of Toga -- Stockfish
supports Chess960, can also specify the number of threads to use (currently Toga
requires a special patch/hack to do this), and is also the strongest open source
chess engine out there (check CCRL).

Original comment by firepot...@gmail.com on 26 Dec 2009 at 1:03

GoogleCodeExporter commented 9 years ago 
Oh and also Stockfish supports "go infinite". From what I can tell Toga also 
supports
"go infinite" -- I'm using Toga II 1.4.1SE (patched with the threads option 
hack --
see http://alpha.uhasselt.be/Research/Algebra/Toga/linux_versions/ and
http://alpha.uhasselt.be/Research/Algebra/Toga/linux_versions/patch_posix.p for 
the
patch).

Part of the problem with all of this is i need a bunch of versions:
Mac OS X: 
need g4/g5 PPC version.
need intel version.
need intel x86_64 version.

Linux 
need ppc version
need x86 version
need x86_64 version

solaris:
need x86 version
need SPARC version

windows:
need x86 version 
(not sure what i need for windows 7)

Currently I can load up and compile:
Mac OS X ppc version,
linux x86_64
linux x86
Possibly windows if i am in a good mood.

I'm looking at Stockfish 1.5.1's Makefile right now in front of me, and it has 
build
targets for OSX PPC32/PPC64, x86 x86_64, etc. I'm quite sure Stockfish is one 
of the
most portable UCI engines out there.

Glaurung (v. 2.2), which Stockfish is based on, came with binaries for Linux, 
OS X,
and Windows. Link: http://www.glaurungchess.com/glaurung22.zip. So, Stockfish
shouldn't be any more different...

ok I will check it out.

btw just for people who read this I added this to the FAQ:

I can't get TogaII or Fruit to work. They dont do anything.

TogaII and fruit do not accept the 'go infinite' command. You can fix this. 
Open a game and click the 
calculator icon to bring up the chess engine analysis. After that click the 
settings button. Remove the infinite 
parameter from the Go Analysis Parameters Field at the top and click save. You 
should now recieve analysis.

Here is Jim Ablett's page, which has the source for Stockfish (1.6 just came 
out,
apparently): http://homepages.tesco.net/henry.ablett/jims.html

RE: the "go infinite" command -- Just wanted to add, Toga II 1.4.1SE does 
accept the
"go infinite" command. I tried it out by hand in the console, and it works. I 
have
the source for Toga II 1.4 beta5c as well in front of me, and it also has code 
to
handle the "infinite" command, so that version should also work as well... Did 
you
try it out manually from the console?

Hmm, I think there's a bug here, specifically:

UCIEngine.java, @ line 276: 
            if (StringUtils.isNotBlank(options)) {
                send("go");
            } else {
                send("go " + options);
            }

Raptor is sending the "go" command by itself. This, apparently, is exactly the 
reason
for the bug reported in Issue 413 (if you type just "go" to Glaurung/Stockfish, 
it
only analyzes to depth 2 -- this is after sending "setoption name OwnBook value
false", so it's not book-related).

I haven't looked at all of the code, but, sending "go" by itself should not be 
the
default. I think "go infinite" should be the default command.

I've tested Stockfish 1.6 with some positions, but currently it is probably not 
what
we want because it seems to give a dead even "0" score for most positions 
(probably a
bug with how it displays the eval). Rather, I recommend Glaurung 2.2
http://www.glaurungchess.com/glaurung22.zip for the time being (it comes with
binaries for Linux, Windows, and OS X -- for both 32 and 64-bit) right now as it
gives a more accurate score immediately upon analyzing a position (and it's 
still
stronger than any Toga variant out there).

Scratch that -- the authors of Stockfish have released a new version, 1.6.2, 
which
fixes this bug. Link to Stockfish:

Here is a link to probably the most up-to-date rating list of chess engines
(commercial, free, open source) out there: 
http://www.computerchess.org.uk/ccrl/4040/

Notice how Stockfish dominates in the open source lists.

Looks like the original question is answered: Raptor will not be bundled with 
an engine.

FYI, I think the Stockfish zero evaluation bug was fixed in the last few months.
