This is the code described in the book, along with generators of random instances and test drivers.
First, there is a Makefile that tests every model in the book. The
reader should run a make before making any change to the code to
verify that everything is working.
The only change that may be
required is to change the value of the PYTHONPATH variable to
indicate where is located Google's or-tools. This variable is set on
the first line of the Makefile.
For each section of the book, the structure is identical. Consider,
for instance the chapter Staffing. The code in the book can be found
in the file staffing.py; in the same file a generator of problem is
included. And in the file test_staffing.py there is a driver that
generates a problem and solves it. The reader can use this as an example
on how to use the models.
