However, your problem description is so brief that it is not possible to really tell whether the NLP procedure is what you need to address your problem. A brief description of the NLP procedure is as follows: "The NLP procedure (NonLinear Programming) offers a set of optimization techniques for minimizing or maximizing a continuous nonlinear function f(x) of n decision variables, x = (x_1,...,x_n)^t with lower and upper bound, linear and nonlinear, equality and inequality constraints." I cannot provide any assistance regarding how to use the NLP procedure. The best that I can do is call your attention to its existence so that you can work through the documentation to determine whether it is the right procedure for your problem. If it is, then you will have to figure out how to use the procedure to solve your optimization problem.
