OR-Tools

OR-Tools is open-source solving technology designed to tackle the world’s toughest problems in vehicle routing, flows, integer and linear programming, and constraint programming.

Get started

A community app is a great place to get started with the OR-Tools integration. OR-Tools bundles several solvers, so you do not need additional installations when running locally or in Cloud. Some of the solvers included are:

• CLP
• GLOP
• PDLP
• SCIP

Make sure to specify the python runtime in your app’s app.yaml manifest:

# This manifest holds the information the app needs to run on the Nextmv Cloud.
type: python
runtime: ghcr.io/nextmv-io/runtime/python:3.11
# List all files/directories that should be included in the app. Globbing
# (e.g.: configs/*.json) is supported.
files:
  - main.py
python:
  # Packages the app depends on need to be listed in a requirements.txt file
  # that is referenced here. All listed packages will get bundled with the app.
  pip-requirements: requirements.txt
