Histograms of solutions for the multistart of FSQP for the chemotaxis related examples. Results obtained from 300 runs from randomly generated initial control profiles. A comparison of optimal solutions obtained by means of ρ = 7 piecewise constant and linear control interpolations is presented. For both OCP1 (a) and OCP2 (b) the best reported value was obtained with piecewise linear interpolation.
