6b76ebc2ca Support for binpack format in sfenreader in learner. Automatically detect file extension and choose the correct reader (bin or binpack) 2020-09-10 21:19:37 +09:00
Tomasz Sobczyk
020e66d2e6 Add "sfen_format" option in gensfen. Valid values are "bin" and "binpack". It determines the output format of the sfens. Binpack is a highly compressed formats for consecutive sfens. Extension is now determined by the used format, output_file_name should contain just the stem. 2020-09-10 21:19:37 +09:00

0405f35403 Double probability of using classical eval 
This patch doubles the moderate imbalance threshold and probability of using classical eval.
So now if imbalance is greater than PawnValueMg / 4 then there is a 1/8 chance of using classical eval.

d2562cde12 Always re-enable NNUE after "bench". 
Restore the default NNUE setting (enabled) after a bench command.
This also makes the resulting program settings independent of the
number of FENs that are being benched.

Fixes issue #3112.

closes https://github.com/official-stockfish/Stockfish/pull/3113

No functional change.

fc27d158c0 Bug fix in do_null_move() and NNUE simplification. 
This fixes #3108 and removes some NNUE code that is currently not used.

At the moment, do_null_move() copies the accumulator from the previous
state into the new state, which is correct. It then clears the "computed_score"
flag because the side to move has changed, and with the other side to move
NNUE will return a completely different evaluation (normally with changed
sign but also with different NNUE-internal tempo bonus).

The problem is that do_null_move() clears the wrong flag. It clears the
computed_score flag of the old state, not of the new state. It turns out
that this almost never affects the search. For example, fixing it does not
change the current bench (but it does change the previous bench). This is
because the search code usually avoids calling evaluate() after a null move.

This PR corrects do_null_move() by removing the computed_score flag altogether.
The flag is not needed because nnue_evaluate() is never called twice on a position.

This PR also removes some unnecessary {}s and inserts a few blank lines
in the modified NNUE files in line with SF coding style.
