Glaurung 2-epsilon

[Vempele]

Reproduced the problem in more debuggable conditions:

Perft from 2 onwards returns wrong numbers in [d]r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq -

2. 1987 (should be 2039 according to Sharper)

divide 1 in the position after e1f1 returns the correct moves (43 instead of the 42 above). I don't suppose there's a command to get a perft tree dump, Tord?

Reproduced the problem in more debuggable conditions:

Perft from 2 onwards returns wrong numbers in [d]r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq -

This is very strange. My Mac OS X executable has no problems:

Code: Select all

position fen r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq -
perft 5
perft(1) = 48, time = 0
perft(2) = 2039, time = 1
perft(3) = 97862, time = 8
perft(4) = 4085603, time = 274
perft(5) = 193690690, time = 12277

I have no idea what the problem could be. "divide 2" also gives the correct output for me.

I don't suppose there's a command to get a perft tree dump, Tord?

No, there isn't - I never saw a need for it until now. Perhaps I should add it in order to solve this strange problem.

Thanks for making me aware of this!

Oops, false alarm. I tried again, and got the correct result. I must have originally entered the fen wrong. Sorry.

Being able to examine the entire search tree would still help.

Just in case, here are the nodecounts and best moves from the from the position (this time I made it the start position in order to avoid more input errors)

Code: Select all

2. 12341 e2a6 
3. 15543 e2a6
4. 18396 e2a6

Hi Tord,

do you think it will be a long wait for us before the finished product?

Hi Graham,

As a rough estimate, I guess you will have to wait at least six weeks and at most six years, but I wouldn't bet on it.

A good answer!

Keep up the good work Tord.

Regards, Graham.

The 64 bit build also succeded with one extra warning somewhere. I couldn't see if it would run though as my 64 bit OS beta has expired.

[Martin Thoresen]

Anyone able to email me a working windows executable? mordor(at)halden.net

[Tord Romstad]

Hello Martin!

Anyone able to email me a working windows executable? mordor(at)halden.net

It seems slightly odd to mail Glaurung to Mordor rather than Angband, but OK.

I think there will quite soon be an official Windows binary, BTW.

Tord

[Martin Thoresen]

Tord,

Angband doesn't exist as far as I know in the 3rd era of Middle Earth...

And Glaurung still exists for some weird reason!?
Wasn't he slain by Turin? I can't completely remember...

So the only place he'll be emailed must be to mordor!

I'm sure Saurun would be pleased to meet an old friend...
A shame Morgoth is behind locks in the oblivion of Mandos' halls.

I am sure he could have wrecked some havoc in the pieceful lands of the Hobbits.

[revengeska]

Hey Tord.

I'm running Fedora Core 6 64 bit Linux. I compiled Glaurung 2 successfully (with 2 warnings) using the Makefile, but unfortunately I can't get it to work with the Jose chess GUI nor Xboard using Polyglot. Here are the 2 warnings:

search.cpp:122: warning: ‘<unnamed>::FailedReductions’ defined but not used
search.cpp:141: warning: ‘<unnamed>::MaxNodes’ defined but not used

Also, I compiled your Glaurung 1.2.1 as well, and while it works, it's considerably slower than even a 32 bit engine. Check your e-mail for details on that, I sent it not too long ago.

I guess that's quite a lot of help I'm asking for Thanks though:)
