Test Problems for the Second Part of the Strategy Comparison 341 Figure A.14: Graphical representation of Problem 2.21 for n =2 F (x) ==2 4 6 8 10= Powell also ended the search without making any signi cant improvement on the initial condition. Both the simplex method of Nelder and Mead and the complex method of Box also had trouble in the minimum search in their cases the initially constructed simplex or complex collapsed long before reaching the minimum, again near one of the corners. Problem 2.22 Objective function: Minimum: Start: F (x) = nX i=1 jxij + nY i=1 jxij for n =5 x i =0 for i = 1(1)n F (x )=0 x (0) i =10 for i = 1(1)n F (x (0) ) = 100050 The simplex and complex methods did not nd the minimum. As in the previous Problem 2.21, this is due to the sharply pointed corners of the contours. The variable metric strategy also nally got stuck at one of these corners and converged no further. In this case the discontinuity in the partial derivatives of the objective function at the corners is to blame for its failure.
