test 49900, aka 49.9 (currently run3 on main LCZero page) is a test of the potential for forced opening diversity to benefit Elo for Leela

Special thanks to Discord members fersbery for coding the needed lc0 update, crem for facilitating the generation of games via the automated client system, and aart for extensive discussions about plans and ideas.

test 49900 has been now been converted to an RL run, though new nets will appear slowly (perhaps one every day or two?) because of low game contribution relative to games per network.

Change in plan - with help from fersbery, this is in the process of being converted to something much closer to a standard RL run, though probably with more intermittent training (and training done on my machine). Game contribution will be the same as before.

Results so far are promising but still not overwhelmingly clear. Stay posted!

If these results look good, I support the idea of having a future T5x run use some form of forced opening diversity, though it might be wise to further test how broad and deep the book should be before it starts. Ideas are welcome.
