Mixed Integer Programming

This chapter extends the model developed in Chapter 10 to a Mixed Integer Programming (MIP) problem. It describes how to

• define different types of discrete variables,
• get the MIP solution status and understand the MIP optimization log produced by Xpress Optimizer.

Chapter 6 shows how to formulate and solve the same example with Mosel and in Chapter 16 the problem is input and solved directly with Xpress Optimizer.
