Invictus chess engine r228

[Edsel Apostol]

Compiles nicely on Linux with some minor modifications. Testing it against Fruit 2.1 right now

It is probably too weak for Fruit right now. The eval is just material, pst and mobility.

May I know what are your changes for Linux and if I could package your Linux build as well? I currently don't have a Linux environment to make a build.

I've decided to release my new chess engine Invictus. It's almost 2 months old now.

Features:
...
SMP support with modified ABDADA and my own improvements (http://www.tckerrigan.com/Chess/Parallel_Search/How_To/)
NUMA support (Thanks Andrew Grant for the code)

Hello Edsel, is there any chance for a release w/o popcount?

I've updated the release. There are three builds now:

pext w/ popcnt
magic w/ popcnt
magic w/o popcnt

Thanks a lot Edsel!

This engine should be a good starting point for other programmers wanting to write their own engine. Estimated strength is around 2400 CCRL/2200 CEGT.

Great, many thanks!
