Fig. 8.

Profitability of the original optimal sequence and the actual optimal sequence changing for different values of the crop–weed competition function perturbation parameters Δ_loc (left) and Δ_sc (right). On the right, Δ_loc is set constant to its most sensitive value 5, rather than its default value while Δ_sc is varied. In each case, the region where the two lines overlay corresponds to the region where the original optimal sequence is still the actual optimal sequence for the changed competition parameter value.
