Detailed Description

Example with linear equality and inequality constraints.

Example 5 function evaluation progam. This function evaluation expects its input to come from a text file, and it writes its output to to a text file.

The test problem is:

$\begin{array}{ll} {\rm min} & (x_1 - 10)^2 + (x_2 - 10)^2 + (x_3 - 10)^2 + (x_4 - 10)^2\\ \mbox{s.t.} & -10 \le -x_1 - x_2 - x_3 -x_4 \\ & x_1 - x_2 + x_3 - x_4 \le -1 \\ & 2x_1 + 2x_3 \le 9 \\ & 2x_1 + 2x_3 - 7x_4 = 3 \\ & -10 \le x_1 \\ & -10 \le x_2,x_4 \le 10 \\ & x_3 \le 10 \\ \end{array}$

All of the linear inequality, linear equality, and bound constraints are defined in the file example4.apps, where we also define the scaling and initial point as:

$s = \begin{bmatrix}1\\1\\1\\1 \end{bmatrix}, \quad x^{(0)} = \begin{bmatrix}-1\\1\\-1\\-1 \end{bmatrix}$
