Open AccessExtensions to generalized disjunctive programming: hierarchical structures and first-order logic
Optimization problems with discrete–continuous decisions are traditionally modeled in algebraic form via (non)linear mixed-integer programming. A more systematic approach to modeling such systems is to use gen...

Open AccessIterative MILP algorithm to find alternate solutions in linear programming models
We address in this paper linear programming (LP) models in which it is desired to find a finite set of alternate optima. An LP may have multiple alternate solutions with the same objective value or with increa...
