8.0.0
8.0.0 Release
Yes it has been a quite while and I haven't worked on Rice much. However, there's been some search improvements made about 8-9 months ago and recently Rice has got a new net hexadecane_512_v2.net which has new architecture of 16 * 768 -> 512x2 -> 1. Reducing down to 512x2 from previous 768x2 hidden layer, has given quite a speed boost along with the strength from more buckets.
Elo difference should be ~70 elo from previous version, I haven't got time to test it so yeah that's the estimate.
As usual, binaries built for windows are given.
rice-8.0.0-v2.exe for POPCNT, SSE3, SSE4.1, SSE4.2, SSSE3 CPUs.
rice-8.0.0-v3.exe for AVX, AVX2, BMI1, BMI2 CPUs.
The speeds of these binary tested on i7 14700KF are:
rice-8.0.0-v2.exe ~0.95 MNPS
rice-8.0.0-v3.exe ~3.21 MNPS
If you face any bugs, feel free to open an issue and I'll look into it.
Cheers!
