I still use Stockfish PA GTB daily on my analysis, and it continuously provides better analysis than Stockfish 9, Houdini 6, Komodo 10, or McBrain 4, all who are at least 100 elo stronger or more, thanks to PA GTB's self-learning.

Unfortunately it may be too much to ask for, considering implementing PA seems to be a monumental work and would require a couple weeks of time.

I was actually referring to Kelly Kinyama's implementation.

Oh, that's "result learning", for the "elo chasing".

I wonder how Kelly Kinyama's implementation differs from Romichess's. Let's implement both and do some testing! :D

In his own words: "is what we do to a transposition table [but] to a hard drive, not main memory." That sounds closer to SF PA GTB's approach, rather than RomiChess', but at least is already in "SF code" which should make it easier to incorporate into McBrain.

Difficulty aside, I would also like to test both ways.

Well, the Stockfish derivative "SugaR Xpro" already implements that, and in practice it's just like never unloading the engine, Position Learning is something else.

Though I agree something like this would be easier to implement than actual learning, I'd really love any modern strong engine to implement Jeremy Bernstein's Persistent Analysis approach, because I find ridiculous to have to use some 4 year old engine for these purposes (story repeats itself, 4 years ago I was still using Rybka 3 Persistent Hash for this...)

Not exactly the same, manually saving the hash, will only give you what was allocated in RAM. Here you're automatically using the hard drive all the time, which means having several TBs of space (depending on your HDD size), to save stats about any position ever played by the engine. Furthermore, it only needs 24 bytes per position, the space savings (compared to a full hash dump) are astronomical. Granted, a full hash stores more information that "could" be useful, but in practice, it will mostly be useless.

+1 It is a vastly superior method to the hash dump everyone else is using these days.

Which is why I'm surprised to see that fork under-maintained.
