Rudim v3.0.1 and v3.0.2 were released in the past week
https://github.com/znxftw/rudim/releases/tag/v3.0.1
https://github.com/znxftw/rudim/releases/tag/v3.0.2

Highlights :
- 3 million+ self play games generated and used to retrain Rudim's NNUE (trained purely on self play from v0 onwards)
- Moved from the initial 32 HL NNUE > 64 (3.0.1) > 128 (3.0.2)

Approximate Gain from previous versions
v3.0.0 > v3.0.1 : ~100 ELO
v3.0.1 > v3.0.2 : ~150 ELO
Totally atleast ~250 - 300 ELO gain from 3.0.0

To Rudim versions:

Are hash tables supported? The Shredder GUI doesn't prompt for the hash table size when the engines start up—that's unusual.

For the moment:
Thanks for Rudim!

Hi Frank!

Yes Rudim has a TT, but haven't implemented the UCI option for a custom TT size at the moment (it's hardcoded to 64mb)
Had a tracking issue, will work on it in 3.0.3 / 3.0.4. (Some other UCI commands like ponder, mate are also pending, but all the core UCI commands are present)

Thanks Frank, you beat me to it !

Rudim 3.0.3 is released.
Quite a few bug fixes, and optimizations to the accumulator.
New network, but the new network is more or less similar strength to the previous net (+5-10~ ELO)
Most of the ELO gain this time is from the optimizations and fixes.
