Here, the abbreviation semi refers to VEs identified with the semi-automatic search, and auto refers to the automatic search. If the element combination of the semi-automatic VE was tested during the automatic search, the corresponding cost function value is displayed in the column semi in auto. If not, this column holds an ’-’. An ’x’ marks cases, where no suitable VE was identified. The average is calculated for columns holding at least three values
