class pyomo.gdp.plugins.between_steps.BetweenSteps_Transformation[source]

Bases: Transformation

Transform disjunctive model to equivalent MI(N)LP using the between steps transformation from Konqvist et al. 2021 [1].

This transformation first calls the ‘gdp.partition_disjuncts’ transformation, resulting in an equivalent GDP with the constraints partitioned, and then takes the hull reformulation of that model to get an algebraic model.
