Fishtest Tuning Framework The purpose of the code is to allow developers to easily and flexibly setup SF for a tuning session. Mainly you have just to remove 'const' qualifiers from the variables you want to tune and flag them for tuning, so if you have: int myKing = 10; Score myBonus = S(5, 15); Value myValue[][2] = { { V(100), V(20) }, { V(7), V(78) } }; and at the end of the update you may want to call a post update function: void my_post_update(); If instead of default Option's min-max values, you prefer your custom ones, returned by: std::pair<int, int> my_range(int value) Or you jus want to set the range directly, you can simply add below: TUNE(SetRange(my_range), myKing, SetRange(-200, 200), myBonus, myValue, my_post_update); And all the magic happens :-) At startup all the parameters are printed in a format suitable to be copy-pasted in fishtest. In case the post update function is slow and you have many parameters to tune, you can add: UPDATE_ON_LAST(); And the values update, including post update function call, will be done only once, after the engine receives the last UCI option. The last option is the one defined and created as the last one, so this assumes that the GUI sends the options in the same order in which have been defined. closes https://github.com/official-stockfish/Stockfish/pull/2654 No functional change.
