Reporting results – attributes

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 variable attributes to obtain the name and solution value for each variable:

  for v in m.getVars():
    print(v.varName, v.x)

We can also query the objVal attribute on the model to obtain the objective value for the current solution:

  print('Obj:', m.objVal)

The names and types of all model, variable, and constraint attributes can be found in the online Python documentation. Type help(GRB.Attr) in the Gurobi Shell for details.
