Figure 2From: Efficient classification of complete parameter regions based on semidefinite programmingMaximal possible parameter perturbation. The size η of the maximal possible perturbation in the example given in the text is shown as a function of k1 and k3 (here, k2 = 1). The size of the perturbation increases with the distance from the feasible region and can be used to further refine the search directions in parameter space.Back to article page
