Reporting results - attributes
Once the optimization is complete, we can query the values of the
attributes. In particular, we can query the VarName and X
attributes to obtain the name and solution value for each variable:
System.out.println(x.get(GRB.StringAttr.VarName)
+ " " +x.get(GRB.DoubleAttr.X));
We can also query the ObjVal attribute on the model
to obtain the objective value for the current solution:
System.out.println("Obj: " + model.get(GRB.DoubleAttr.ObjVal));
The names and types of all model, variable, and constraint attributes
can be found in the Attributes section of the
Gurobi Reference Manual.
