Suppose you want to solve the following simple example

We need to define two decision variables x1 and x2 and also two constraints (the code is as follows )

Ok, now we know the optimal values of the decision variables and the objective function.

We do need a command to see if the problem was infeasible or optimal

Also we can have a look at the constructed model

the variables and also the constraints

This shows the variable limits and also the value of them. additionally you can see if each variable is fixed or not.

The domain of each variable is visible as well.

The same info is also available for each constraint.

And finally, the model statistics are available here
