GRBEnv()

Environment constructor.

Constructor for GRBEnv object. If the constructor is called with no arguments, no log file will be written for the environment.

You have the option of constructing either a local environment, which solves Gurobi models on the local machine, a client environment for a Gurobi compute server, which will solve Gurobi models on a server machine, or an Instant Cloud environment, which will launch a Gurobi Cloud server and solve models on that server. Choose the appropriate signature for the type of environment you wish to launch.

Note that the GRBEnv constructor will 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). It will also populate several parameters (ComputeServer, TokenServer, ServerPassword, etc.) from your gurobi.lic file.

In general, you should aim to create a single Gurobi environment object 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.
