License for the optimization

For running an optimization, a license is required, in case you use more than ten elements (including nodes and resources). The license will be provided as a JSON definition. In case you run the optimizer as a dependency, you can save this definition as a text file and set it on startup or as String.

 // Via String


 // Or via file

Example of how a license can look like:

  "version" : "7.4",
  "identifier" : "TEST-",
  "description" : "Key provided to by DNA evolutions GmbH",
  "contact" : "",
  "modules" : [ {
    "Module:" : "Date",
    "creation" : "2020-05-25",
    "due" : "2024-05-08"
  }, {
    "Module:" : "Elements",
    "max" : 100
  } ],


Changing any JSON-key (deleting, modifying, or adding) of the license will deactivate the license. The only allowed modification is a formating step, like prettifying the JSON.

In case you are using the docker version of JOptTourOptimizer, you will have to send this JSON definition along with your request.
