GRBEnv.start()


GRBEnv.start()

Start an empty environment. If the environment has already been started, this method will do nothing.

This method will also populate several parameters (ComputeServer, TokenServer, ServerPassword, etc.) from your gurobi.lic file. This method will also check the current working directory for a file named gurobi.env, and it will attempt to read parameter settings from this file if it exists. The file should be in PRM format (briefly, each line should contain a parameter name, followed by the desired value for that parameter).. After that, it will apply all paramter changes specified by the user prior to this call. Note that this might overwrite parameters set in the license file, or in the gurobi.env file, if present.

After all these changes are performed, the code will actually activate the environment, and make it ready to work with models.

In general, you should aim to create a single Gurobi environment in your program, even if you plan to work with multiple models. Reusing one environment is much more efficient than creating and destroying multiple environments.

Please consult the parameter section for a complete list of Gurobi parameters, including descriptions of their purposes and their minimum, maximum, and default values.
