# Question

Consider the example for applying SUMT given in Sec. 13.9.

(a) Show that (x1, x2) = (1, 2) satisfies the KKT conditions.

(b) Display the feasible region graphically, and then plot the locus of points x1x2 = 2 to demonstrate that (x1, x2) = (1, 2) with f (1, 2) = 2 is, in fact, a global maximum.

Consider the following function: Show that f (x) is convex by expressing it as a sum of functions of one or two variables and then showing (see Appendix 2) that all these functions are convex. Reconsider the convex programming model with an equality constraint given in Prob. 13.6-11. (a) If SUMT were to be applied to this model, what would be the unconstrained function P(x; r) to be minimized at each iteration?
