Abstract: Highlights•A logic-based discrete steepest algorithm for generalized disjunctive programs.•By reformulating ordered Boolean variables, a lattice of subproblems can be explored.•Ordered Booleans variables are key in process optimization and chemical engineering.•Computational results show the efficiency of the algorithm against compared to MINLP methods.•Open-source implementation and algorithmic enhancements are explained and provided.
