Commit ID 2c5dfb312205de03239cb15e79b501789c4cd067
Author Joost VandeVondele

Assign improving only once Avoid duplicated code after recent commit "Use evaluation trend to adjust futility margin". We initialize the improving variable to true in the check case, which allows to avoid redundant code in the general case. Tested for speed by snicolet, patch seems about 0.4% faster. No functional change. Note: initializing the improving variable to false in the check case was tested as a functional change, ending yellow in both STC and LTC. This change is not included in the commit, but it is an interesting result that could become part of a future patch about improving or LMR.
