Creating the environment
The first executable statement in our example obtains a Gurobi
environment (using the
// Create an environment GRBEnv env = GRBEnv(true); env.set("LogFile", "mip1.log"); env.start();
In this call we requested an empty environment, chose a log file, and started the environment.
Later calls to create an optimization model will always require an environment, so environment creation is typically the first step in a Gurobi application.
