new engine - Fizbo - could you please test it?

[ymatioun]

I have created a chess engine - Fizbo - could you please test it and add it to CCRL?

Executable can be downloaded from:
https://sites.google.com/site/fizbochessengine/

Features:
uses Winboard protocol
runs on 1 CPU core
requires x86 Windows
requires "popcount" and "bitscanforward" instructions
main transposition table size if fixed at 128 Mb; total RAM use is around 144 Mb
this version does not use endgame bit-bases or table-bases
no opening book

Estimated strength is around 2800 ELO (it plays about even with Fruit 2.31).


Thank you very much, Youri Matiounine.

I only have 64-bit Windows.
Any chance that you could provide a compile for that?

It actually is 64 bit executable, i just incorrectly listed it is as x86. I even called the executable fizbo11x64, to remember it. I apologize for the confusion.

On my i5 I get this.
Fizbo will not run on this computer - I use Windows 7 Home Premium.

I don't know what is causing the problem. I just tried to run it on my laptop (i5+Win7) - it works fine. And for this compile i make some changes to ensure portability - turned off endgame bit-bases, turned off all logging, included runtime C++ libraries into the executable. I'm all out of ideas.

If you somehow come up with a 64-bit exe that works for me, I'll include Fizbo in my upcoming 47th Amateur Division 3 tournament.

It seems to need a modern CPU to work. It works on my Intel Sandybridge laptop, but not on my AMD Phenom II X6. Perhaps it needs AVX support in the CPU.

[ymatioun]

This is it! Thanks for pointing it out to me.
I realized that the executable was created with "/AVX" compiler switch.
I recompiled it without it, and i think now it should work on any CPU supporting "popcount" instruction - any Intel "i" CPU.
The new executable is posted at "https://sites.google.com/site/fizbochessengine/", please use it for testing.

Thank you very much, Youri.

It runs now on my AMD Phenom II X6.

Youri - just for our engine notes, what country are you from?

[ymatioun]

I live in New York, USA.

Thanks.

I just added a 64-bit executable that does not use "popcount" instruction. This should work on any 64-bit CPU.

Hi i am testing your engine on my Win8-64 i-7 4-cpu 3.4 Ghz desktop. It makes the first move fairly quickly as White, but not as Black.... don't know why. it sometimes takes a long time to make it's black move.
It's that way with the regular and the no pc version. So i don't play it on quick time settings. I'm going to test it using time controls of 1+1, then 5+2, 15+3, and maybe some 40 moves 40 minute ones.
I see in CCRL 40/40 standings it has a very respectable 51st place with 51 Fizbo 1.1 64-bit , rated 2778.
I'll let you know how my tests come out. I'm testing it against about 60 other engines rated 2700 and up.

I tested Fizbo 1.2 against about 65 other computers rated 2800 and above at time levels of 1 min 1 sec added.
It scored 42/132 games, which would give it a rating of between 2700-2900, depending on how you score things. The ones it tied were rated right around 2900.
I'll try some tests at 15 1 and see how it goes.
