Subject: Use (strict) greater-than-operator for 'improving'
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;ds=sidebyside;h=f63d112c710fcd38c9d4946f38603b9c2b4689a4;hp=f63d112c710fcd38c9d4946f38603b9c2b4689a4;p=stockfish

Use (strict) greater-than-operator for 'improving'

Currently on a normal bench run in ~0,7% of cases 'improving' is set to
true although the static eval isn't improving at all, just keeping
equal. It looks like the strict gt-operator is more appropriate here,
since it returns to 'improving' its literal meaning without sideffects.
