Up Topic The Rybka Lounge / Computer Chess / Stockfish almost half way to 12 already

Graph below shows Stockfish 8-cores 06-06-2020 +23.7 Elo to Sf 11, 1-core +19.5.
Traditionally the next version is 50 Elo above the last (I think the source varies each time, I am not sure).
Interestingly most of the gain has been rapid in the most recent half of the time since 11.

Regression Tests

All the graphs below are results of tests in the fishtest framework, exclusively from 40.000 games tests at long time control (60sec + 0.6 for single core, 30sec + 0.3 for 8 cores tests). Results have thus a confidence interval of +- 2 Elo. Note: since 21.11.2019 single core tests are played over 60,000 games.

    Progress rate for the current development version (SF12 dev):

> Iterestingly most of the gain has been rapid in the most recent half of the time since 11.


This might be Covid-19 related, people had a bit more free time on average last months.
If it's indeed Covid related it would mean SF is nowhere near a plateau yet, we just need a bunch of good developers spending some extra time on writing patches ;-)
