a Number of combinations of EMs, n f, on the left axis and computation time for the evaluation of the combinations, t f on the right axis against numbers of factors, n Fac. Black circle and continuous line: Theoretical possible number of combinations; Black/Gray plus and continuous line: Combinations evaluated/Computation time by the branch and bound approach in case of no noise; Black/Gray square and dashed line: Combinations evaluated/Computation time by the branch and bound approach in case of 2 % noise; Black/Gray star and dashed-dotted line: Combinations evaluated/Computation time by the branch and bound approach in case of 10 % noise. b Computation time for the evaluation of one EM, t f/n f. Black plus and continuous line: No noise; Black square and dashed line: 2 % noise; Black star and dashed-dotted line: 10 % noise
