Hi all!
I'm glad to announce that Supernova 2.4 is released.
https://github.com/MichaeltheCoder7/Sup ... s/tag/v2.4
Changes:
Added lazy SMP. Supernova can now use more than one CPU when thinking!
Fixed a Zobrist hashing bug regarding en passant.
Fixed an issue in static exchange evaluation.
Various optimizations.
Changed data type in the 8x8 board.
Encoded castling rights.
Made quit command more stable.
Compiled with GCC 11.2.
Testing Results:
Supernova 2.4 (4 CPUs) vs Supernova 2.3:
Time control: 10+0.1
Games: 910
Elo difference: 152.2 +/- 18.1
Supernova 2.4 (1 CPU) vs Supernova 2.3:
Time control: 10+0.1
Games: 3000
Elo difference: 17.2 +/- 9.1
Please let me know if you found any issues or bugs.

Re: Supernova 2.4
Not planning for that at the moment. It might be complicated since I need another evaluation for FRC.

Re: Supernova 2.4
Thanks for testing. Unfortunately, with 1 CPU, elo gain is not much so it needs a lot more games to be accurate. It's probably more worthwhile to test with 4 CPUs.Rebel wrote: ↑Wed Sep 15, 2021 4:14 pm Supernova 2.4 : -7 elo
