Adding variables to the model
The next step in our example is to add variables to the model.
# Create variables
x = m.addVar(vtype=GRB.BINARY, name="x")
Variables are added through the addVar() method on a model
object (or addVars() if you wish to add more than one at a time).
A variable is always associated with a particular model.
Python allows you to pass arguments by position or by name. We've
passed them by name here. Each variable gets a type (binary), and
a name. We use the default values for the other arguments.
Please refer to the online help (help(Model.addVar)
in the Gurobi Shell) for further details on addVar().
