OR-Topas

Operations Research Toolkit for Pyomo Alternative Solutions

Overview

OR-Topas provides a python toolkit for generating and analyzing alternative solutions for pyomo models. This library is adapted from the pyomo.contrib.alternative_solutions and pyomo.contrib.benders libraries. OR-Topas extends the solution pool definition from pyomo, and it includes new Benders implementations that support generation for alternative solutions.

Testing

OR-Topas tests can be executed using pytest:

cd or_topas
pytest .

If the pytest-cov package is installed, pytest can provide coverage statistics:

cd or_topas
pytest --cov=or_topas .

The following options list the lines that are missing from coverage tests:

cd or_topas
pytest --cov=or_topas --cov-report term-missing .

Note that pytest coverage includes coverage of test files themselves. This gives a somewhat skewed sense of coverage for the code base, but it helps identify tests that are omitted or not executed completely.
