If you're interested in discussing OR-Tools or Operations Research, please visit our forum.

Some guidelines for effective conversations:

  • If you're having trouble solving an optimization problem, please include the smallest possible program that demonstrates the trouble, and which version of OR-Tools (e.g., v9.5) you're using.
  • If you're having trouble installing OR-Tools, please include the error message in your post and mention which version of OR-Tools you're using as well as your operating system (e.g., Ubuntu 20.04, 64 bit).
  • If you're wondering how to model a problem, please look at our examples and (for CP-SAT) samples on GitHub, and on this site. It's good practice to start with a small example and gradually add complexity.
  • If you are also posting on StackOverflow or GitHub, please include cross-references to benefit future readers.
  • Be nice, and assume the best of intentions from other list members.

We release improvements to OR-Tools frequently. We announce those on the forum and our releases page. If you want to contribute to the code, please create a pull request on GitHub.
