Smoothly change playing strength with skill level. (#2142) The current skill levels (1-20) allow for adjusting playing strengths, but do so in big steps (e.g. level 10 vs level 11 is a ~143 Elo jump at STC). Since the 'Skill Level' input can already be a floating point number, this patch uses the fractional part of the input to provide the user with fine control, allowing for varying the playing strength essentially continuously. The implementation internally still uses integer skill levels (needed since they pick Depths), but non-deterministically rounds up or down the used skill level such that the average integer skill corresponds to the input floating point one. As expected, intermediate (fractional) skill levels yield intermediate playing strenghts. Tested at STC, playing level 10 against levels between 10 and 11 for 10000 games level 10.25 ELO: 24.26 +-6.2 level 10.5 ELO: 67.51 +-6.3 level 10.75 ELO: 98.52 +-6.4 level 11 ELO: 143.65 +-6.7 http://tests.stockfishchess.org/tests/view/5cd9c6b40ebc5925cf056791 http://tests.stockfishchess.org/tests/view/5cd9d22b0ebc5925cf056989 http://tests.stockfishchess.org/tests/view/5cd9cf610ebc5925cf056906 http://tests.stockfishchess.org/tests/view/5cd9d2490ebc5925cf05698e No functional change.
