Nonlinear Programming Using CppAD and Ipopt: Example and Test
#############################################################

Purpose
*******
This example program demonstrates how to use :ref:`ipopt_solve-name` to
solve the example problem in the Ipopt documentation; i.e., the problem

.. math::

   \begin{array}{lc}
   {\rm minimize \; }      &  x_1 * x_4 * (x_1 + x_2 + x_3) + x_3
   \\
   {\rm subject \; to \; } &  x_1 * x_2 * x_3 * x_4  \geq 25
   \\
                     &  x_1^2 + x_2^2 + x_3^2 + x_4^2 = 40
   \\
                     &  1 \leq x_1, x_2, x_3, x_4 \leq 5
   \end{array}

Configuration Requirement
*************************
This example will be compiled and tested provided
:ref:`cmake@include_ipopt` is on the cmake command line.

{xrst_literal
   // BEGIN C++
   // END C++
}
