dbbb3fa477 Add info string showing which evaluation is in use 2020-08-02 17:22:19 +02:00
Joost VandeVondele
18686e29c7 Revisit NNUE initialization 
this revisits the initialization of NNUE, basically only changing
the state on the UCI options 'Use NNUE' and 'EvalFile' calling init_NNUE(),
which sets the Eval::useNNUE variable, and loads the network if needed
(i.e. useNNUE is true and the same network is not yet loaded)

init_NNUE is silent (i.e. no info strings), so that it can be called at startup
without confusing certain GUIs.

An error message on wrong setting when asking for (i.e. the net failed to load),
is delayed to the point where everything must be consistent (start of search or eval).
The engine will stop if the settings are wrong at that point.

Also works if the default value of Use NNUE would become true.

6cd70676b4 Update README.md 
Mostly restores the previous README.md with some info and new UCI options, retaining only the info needed for the player.
The valuable training documentation is best preserved elsewhere.

Comments / fixes welcome.

Don't copy NNUE parts of StateInfo when not needed in do_null_move().

is not used, was ~5 Elo before.
