Raphael v3.3 Release

Post by orbitalrm »

Hello!
This is my first time posting here, but I've been developing my chess engine, Raphael, for a while now.
Below is the engine info. It'd be great if someone can test it for CCRL Blitz, 40/15, and maybe even FRC, thanks!

**Raphael 3.3**

- implemented various correction histories
- implemented tt clusters and storing static eval in tt
- made various enhancements to various prunings
- tuned using SPSA
- finetuned net and increased input buckets

No multicore support yet (next release)

- `+133` STC against `v3.1` (`3687` estimated CCRL blitz)
- `+98` LTC against `v3.1` (`3554` estimated CCRL 40/15)

Hello,

I have put it in my testing queue. However, you can't expect all versions to be tested as there are many other engines waiting as well. We'll see how it unfolds.
