get_subproblem

(function from pyomo.contrib.gdpopt.create_oa_subproblems)

pyomo.contrib.gdpopt.create_oa_subproblems.get_subproblem(original_model, util_block)

Clone the original, and reclassify all the Disjuncts to Blocks. We’ll also call logical_to_disjunctive and bigm the disjunctive parts in case any of the indicator_vars are used in logical constraints and to make sure that the rest of the model is algebraic (assuming it was a proper GDP to begin with).
