I would like to seek some advice on modeling the following:
I am currently using Pyomo to generate my MILP model in Pyomo. It seems that it is not possible to cast the integer and binary variables to continuous variables for solving the model as a linear program for obtaining its linear relaxation.
Short of creating a similar model for linear relaxation due to model loading and solution time constraints, I would like to ask if there is any way to invoke the solver from Pyomo to solve the said model as a Linear Program?
