3.5. License settings

To run the standalone edition of MindOpt, you must first obtain a valid license.

3.5.1. Obtain License

MindOpt supports two kinds of authentication methods:

  • Floating License. Checking authentication by the remote cloud server, but run the application locally in your own computer.

  • Local License. License is bound to the cpu-id of your computer.

Ways to obtain the license:

  • If your computer can connect to Internet, we recommend that you use a cloud floating license and obtain the license on cloud authorization . Please buy the service and obtain a “licenseKey’’ by yourself, and configure the floating license file” fl_client.ini ‘’. Now it is charge free for linear programming.

  • If you need to use the solver in a non-networked environment, you can send your application to our email, see Contact us.

Note

  • You can effectively activate MindOpt with either a floating license fl_client.ini or a local license mindopt.lic .

  • When both license files are available, the software will verify mindopt.lic first.

After you obtain the license, perform the following steps.
