Convex generalized disjunctive programming (GDP)
Edited By: Nicholas Schafhauser, Blerand Qeriqi, Ryan Cuppernull
The two most common ways of reformulating a GDP problem into an MINLP are through Big-M (BM) and Hull Reformulation (HR). BM is the simpler of the two, while HR results in tighter relaxation (smaller feasible region) and faster solution times.

Below is an example of the reformulation of the GDP problem from the Theory section reformulated into an MINLP by using the Big-M method.
