 Study Objective:

Many practical tasks are computationally infeasible. The course is about fast algorithms for such problems, both exact and heuristic. Heuristic algorithms tend to be simple to program, but difficult to configure and deploy. Their successful application requires a deeper understanding of their operation and complexity theory. A series of individual works guides the student from simple techniques to solutions of practically significant problems.
