The OPTMODEL procedure, a general purpose optimization modeling language, can also be used for concisely modeling nonlinear programming problems. Within OPTMODEL you can declare a nonlinear optimization model, pass it directly to various solvers, and review the solver result. For more details, see Chapter 5: The OPTMODEL Procedure.
You can solve many different types of nonlinear programming problems with PROC OPTMODEL using its nonlinear solver functionality. For more details about the nonlinear programming solver, see Chapter 10: The Nonlinear Programming Solver.
