New engine releases 2019

[Guenther]

So the last 2 months I've been caught up with the chess programming virus again. Nothing too serious as I don't have much of a test environment (just a quad core laptop). It came to a point where I couldn't do much improvement anymore without doing intensive testing. So here goes the latest version.

Invictus revision 305 now available:

https://github.com/ed-apostol/InvictusC ... s/tag/r305

Last CCRL 40/4 rating is:
Invictus r228 64-bit 4CPU 2376 (+120 vs 1 CPU)!
Invictus r228 64-bit 2256

Latest version should be much stronger! :)

Thanks Edsel.

I need to create my own no/popcnt version though, as non-pext is already too advanced for my old quadcore.

There is a NOPOPCNT define on top of bitutils.h. Maybe I'll upload a non-pext no-popcnt version.

Thanks for the upload, still a makefile would be nice.

NoC by Jorge F. Unfortunately I could not determine his whole name.

Still in progress and still anonymous.
Compiled it a few times for my own, but never succeeded in compiling it with gaviota tbs usage.

Weiss 0.7 released.

This version mostly improves search by better move ordering and adding pruning heuristics. More details in the tag.

That's fine. Unfortunately I am still not trained to compile it myself. May I ask for some Windows executables?

Thanks for adding a message about recognition of the syzygy files :)

Thanks Günther.

I have tried to learn to compile these myself several times but failures led me to lose my interest. Waiting for the kiss of the muse.

I've added 3 windows compiles to the tag. Feedback on whether they work or not would be appreciated

Thanks Terje. All three work for me. Under Shredder 13 I measure the following approximate speeds:

nopop: 1250 knps

pop: 1360

pext: 1430

Günther's compile: 3420 knps
