Gurobi

Gurobi is a commercial solver that can be used to solve large-scale linear (LP) and mixed integer problems (MIP), as well as non-linear problems. Users can quickly identify precise, globally optimal solutions to complex nonlinear problems—from domains such as chemical engineering, electricity flow, and price optimization.

Get started

A community app is a great place to get started with the Gurobi integration. The Gurobi community apps ship with a gurobi.lic.template file that you can modify to include your Gurobi license.

Remove the .template extension and fill in the information with your actual license.

WLSACCESSID=secret-123
WLSSECRET=secret-123
LICENSEID=123

And then include the gurobi.lic file in the app.yaml manifest under files (see the last three lines):

# 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
python:
  # All listed packages will get bundled with the app.
  pip-requirements: requirements.txt

# List all files/directories that should be included in the app. Globbing
# (e.g.: configs/*.json) is supported.
files:
  - main.py
  # If you have a Gurobi license, uncomment the following line and make sure to
  # store your license information in that file.
  # - gurobi.lic

License

The Gurobi-Nextmv integration works with the WLS (Web License Server) licensing model. This means that you need to have a valid WLS Gurobi license to use this solver on the Nextmv Platform. Nextmv does not provide Gurobi licenses.

Languages & runtimes

Supported languages and available runtimes for Gurobi apps are listed in the table below. These properties must be defined in the app manifest for your app to run remotely.
