This course provides knowledge on how to solve complex optimization problems via combinatorial and discrete optimization.


From cost-effective logistics and transport, resource-constrained production planning, better sustainability, and shift scheduling, to learning deep neural networks, optimising real-time markets and designing better treatments to life-threatening diseases, the ability to efficiently obtain good solutions to complex optimization optimization problems has a remarkable impact on individuals, societies, and the world.

This course is an introduction to combinatorial (discrete) optimization, providing an exposition of some of the most central concepts and algorithmic approaches to solving computationally hard optimization problems at large. The course provides background and tools for modelling and solving complex optimization problems via declarative means, in particular linear and mixed-integer programming, as well as local search. Both key mathematical concepts and practical declarative optimization systems are covered.

While the course aims to be relatively self-contained, basic background on fundamental algorithms, linear algebra, and practical programming are key assets for successful completion of the course.

Term/teaching period when the course will be offered:

Autumn term, period II, biannually (first time in Autumn 2018)

Combinatorial search spaces, polynomial-time and NP-hard optimization problems. Linear programming and integer programming. Integer linear programming duality and relaxations. Cutting planes. Branch-and-bound and branch-and-cut. Finite-domain constraint optimization, Boolean optimization, maximum satisfiability. Stochastic local search.

The course does not follow any textbook directly.

Lecture slides and tutorials. A list of recommended supplementary literature will be provided when the course begins.

The course activities may vary per instantiation of the course.

The core study material consists of online lecture materials. Weekly lectures present the core study material with additional explanation and examples. Active participation in the lectures by the students is encouraged to support learning.

Students are given exercise problems geared towards learning the knowledge and skills described in the learning outcomes. Students present their solutions in weekly tutorials either in person or in electronic form (as instructed in the individual exercise sheets) and discuss them with a teacher to obtain feedback. The exercise problems may range from theoretical problems to implementation-level tasks.

Homework assignments (50% of final grade), final exam (50% of final grade), grading scale 0-5.

Contact teaching consisting of 2x 2 h lectures and 1x 2 h tutorials weekly. Other forms of activities, such as programming tasks as homework, are also possible.

Completion requirements: homework and final exam.
