Examples of use

This chapter discusses some example Python scripts that are part of the Xpress Optimizer's Python interface. Most of them are well commented so the user can refer directly to the source for guidance.

Most of these scripts have an initial part in common, which we reproduce here but omit in all explanations below for compactness. These initial lines import the Xpress module itself and the NumPy module, which is used in some of the examples. The first line is to make the print statements, which are in Python 3 style here, work in Python 2.7 as well.

from __future__ import print_function
import xpress as xp
import numpy as np
