AMPL MODELING LANGUAGE AND SYSTEM
for Hillier and Lieberman, Introduction to Operations Research, 12th edition

Free, full-featured AMPL software packages are available to support the 
optimization chapters of the Hillier and Lieberman textbook. Packages 
include the AMPL modeling language and system, the Gurobi solver, and
a variety of other solvers that work with AMPL.

Visit https://ampl.com/licenses-and-pricing/ampl-for-teaching/ to learn 
more and to set up your AMPL and solver software:

** Select "Request AMPL for Courses" for downloading to any Windows, macOS, 
and Linux computers involved in teaching a course, including the personal 
computers of instructors and students.

** Select "Explore AMPL on Google Colab" for running online in the Python 
environment of our AMPL Colaboratory, using Jupyter notebooks supported
by the free Google Colab environment.

Additional instructions and examples for working with spreadsheets can be
found at https://plugins.ampl.com/amplxl.html.
