Halogen 4 release

[Kieren Pearson]

Hi, I have released the next version of Halogen on my github https://github.com/KierenP/Halogen

As part of my requirements to get the engine working with OpenBench I have supplied a makefile, so feel free to compile yourself if you would like. I have supplied a binary on Github.

Code: Select all

Elo change against Halogen 3.0
Single threaded: +150-160 elo (~2200 CCRL)

8 Threads: +131.24 +- 29.68 (95%) against single thread Halogen 4
4 Threads: I would estimate about +70-100 elo

Change-log supplied on Git-hub releases

One question of concern, Halogen will be the lowest ranked 4CPU engine on the CCRL list. Is there a minimum requirement of strength for 4CPU engines that I need to reach in order to be tested as a 4CPU engine?

Hi Kieren

Thank you very much for this new version. I can test it for the blitz list at 4CPU.

Best regards.

No problem under Arena or Shredder but I can't install it under Fritz.

Is it possible it's because my engine supports a 'Threads' command? Looking at http://wbec-ridderkerk.nl/html/UCIProtocol.html the 'official' uci protocol has no mention of threads, so I tried to implement it the same as how Stockfish has done it. Besides that, any ideas what caused this issue?

All other GUI's accept it. My guess is that the name is too long for Fritz (you include your own name in the name). I think if you replace author with 'by' it will be fine.
I have the same problem with SlowChess Blitz Classic, I have to edit its engine file manually. I guess I could have done that with your engine as well.

Oh that wasn't intentional, I think I must have tried to put the id name and author in the same line and I didn't realise they needed to be two separate commands. I'll fix this for my next release

Code: Select all

id name Halogen4.2
id author Kieren Pearson

I edited main.cpp splitting the first cout line in two, compiled it and now Fritz has no problems installing Halogen.
