We consider a class of convex programming problems whose objective function is given as a linear function plus a convex function
whose arguments are linear functions of the decision variables and whose feasible region is a polytope. We show that there
exists an optimal solution to this class of problems on a face of the constraint polytope of dimension not more than the number
of arguments of the convex function. Based on this result, we develop a method to solve this problem that is inspired by the
simplex method for linear programming. It is shown that this method terminates in a finite number of iterations in the special
case that the convex function has only a single argument. We then use this insight to develop a second algorithm that solves
the problem in a finite number of iterations for an arbitrary number of arguments in the convex function. A computational
study illustrates the efficiency of the algorithm and suggests that the average-case performance of these algorithms is a
polynomial of low order in the number of decision variables. |
