New engine: Caissa

[Witek]

Caissa 0.7 has been released!
https://github.com/Witek902/Caissa/releases/tag/0.7

I've implemented and trained custom neural network and completely dropped the one I "borrowed" from SF. This means that Cassia is now a legit and independent engine that can compete in CCRL.
Unfortunately, that means pretty significant Elo drop, but I'll be continuing work on improving it.

Hi Micahel, what do you estimate the current Elo to be?

Hi Micahel, what do you estimate the current Elo to be?

After running short matches with other engines, I estimate Caissa 0.7 to be around 3000-3100 Elo

Caissa 0.8 has been released.
https://github.com/Witek902/Caissa/releases/tag/0.8

There were numerous improvements to evaluation neural network and trainer. It's stronger by around 70 Elo points compared to version 0.7.

Caissa 0.9 has been released.
https://github.com/Witek902/Caissa/releases/tag/0.9

Again, it's stronger by ~70 Elo points compared to version 0.8.

Good to see Caissa making nice progress.

If I may have a suggestion: let the network file names be unique to each version so that I don't have to put each version in a different folder.
