New engine releases 2020

[ydebilloez]

A new release of Belofte is available. Version 2.0.6. This is a rewrite from scratch in C++ respecting UCI.
Tested on Windows/Linux/Mac in 32/64 bit.

You can set the algorithm used in UCI. Please note that current version is not yet respecting time-levels, only depth levels.

It is with great pleasure I announce the release of Halogen 8. In late September, Halogen was added to the OpenBench framework. As a result, Halogen underwent one of its best months of development so far. In self testing, Halogen 8 is approximately 200 elo stronger than Halogen 7.

Halogen 8 features a larger neural network than was contained in Halogen 7, but due to improvements and optimisations runs significantly faster. The current network was trained using a private neural network trainer written in C by @AndyGrant. I can't thank Andrew enough for the work he has done to support the development of Halogen.

Estimated elo: 2800 CCRL blitz.

Great news.

I noticed that OliThink release compilations since version 5.69 won't run anymore on my old hardware.
Therefore I compiled current 5.89 now for no popcount with SSSE3 instructions.

I did the same for Cinnamon 2.31, its release compilations also don't run anymore here.

Both programs versions will be uploaded soon to my usual download site.

Why is it called final release? I hope you won't call it a day.

Thank you, Guenther. I do not have any patches under testing, and I do not plan on working on Combusken.

Test gauntlet already running.

However, I don't understand your decision to quit. The first public release was only a little more than half year ago.

Sad to hear that, Marcin.
Thank you for your efforts, and for sharing your fine engine with us.
