### APOPT

**APOPT** (for **Advanced Process OPTimizer**) is a software package for solving large-scale optimization problems of any of these forms:

- Linear programming (LP)
- Quadratic programming (QP)
- Quadratically constrained quadratic program (QCQP)
- Nonlinear programming (NLP)
- Mixed integer programming (MIP)
- Mixed integer linear programming (MILP)
- Mixed integer nonlinear programming (MINLP)

Applications of the APOPT include chemical reactors, friction stir welding, prevention of hydrate formation in deep-sea pipelines, computational biology, solid oxide fuel cells, and flight controls for Unmanned Aerial Vehicles (UAVs).
