Course content
The course presents the theory and practice of deterministic algorithms for locating the global solution of NP-hard optimization problems. Recurring themes and methods are convex relaxations, branch-and-bound, cutting planes, outer approximation and primal-dual approaches. Emphasis is placed on the connection between methods. As the course progresses, these methods will be applied and illustrated in the development of algorithms for mixed-integer linear programs, mixed-integer convex programs, nonconvex programs, and mixed-integer nonconvex programs. The broad range of engineering applications for these optimization formulations will also be emphasized.
Learning outcome
Knowledge:
The course provides a presentation of the following topics:
- Introduction to the different classes of optimization (Linear Programming - LP, Mixed-Integer Linear Programming - MILP, Convex Nonlinear Programming, Mixed-Integer Convex Programming - MICP, Nonconvex Nonlinear Programming - NLP, and Nonconvex Mixed-Integer Programming - MINLP
- Motivation for Global Optimization
- Background concepts: Convex Optimization, Optimality Criteria for NLPs, Duality Theory and Computational Complexity
- Attaining Global Information: Interval Analysis, Convex and Concave Relaxations
- MILPs - Problem formulation and Branch-and Bound based solution algorithms
- NLPs - Solution using spatial Branch-and-Bound algorithms
- MICPs - Solution using Outer Approximation and Generalized Benders Decomposition
- MINLPs - Solution using Branch-and-Bound based algorithms, Nonconvex Generalized Benders Decomposition and Nonconvex Outer Approximation
Skills:
- Have an understanding of how to formulate and solve optimization problems appropriately using commercial software (e.g. JuMP in Julia, or GAMS)
- Have an overview of the workings behind several state-of-the-art algorithms for various problem classes. Know which algorithms are appropriate for what types of problems
General Competence:
- Learning how to use computational tools to support decision-making for a variety of engineering problems
Learning methods and activities
A hybrid teaching form will be used, where a considerable degree of Self-learning is combined with Q&A Colloquiums with one or more lecturers and the students of this course. As mentioned below, videos from a similar course at MIT will also be made available together with a text book and a considerable set of slides explaining some of the details of the curriculum. The course will also have assignments with solutions.
Further on evaluation
The exam will take the form of a written report based on a project chosen by the student that s related to the PhD research of the candidate, and where the tools and methods provided in this course are utilized.
The grading of the exam will be pass / no pass, where 70 points (of 100) score is required to pass.
Recommended previous knowledge
An introductory course in linear optimization and a similar course in non-linear optimization will give the students a good start. An introductory course in real analysis would be even better, but not expected by the average student in this course.
Required previous knowledge
None
