Gurobi: Save Model After Presolve For Reuse

I'm looking for a way to save a presolved model in gurobi, so that I can save the time necessary for presolving the next time I'm running the model. I have tried to write the model

Solution 1:

It is very uncommon to save the presolved model. The key exceptions are:

1. When you want to understand the presolve transformations
2. For benchmarking when you don't want to repeat presolve

Gurobi lets you access the presolved model, but only from the Python API. Here is some sample code:

from gurobipy import *
m = read("mymodel.mps")
mp = m.presolve()
mp.write("mypresolved.lp")
