Annotation -
Students get an overview of typical usages of graph models in computing. They learn algorithmic methods of solution of graph problems, using the programming techniques presented in the BI-EFA module. They understand algorithms for the key application domains of graph theory (flows in networks, heuristic search, approximation of complex problems, matching problems). Students get basic competence in computer science background: they understand Turing machine models and issues of NP-completeness and NP-hardness.

Aim of the course -

Students will be able to:

Recognize which graph model is appropriate and which algorithm should be used when solving a specific problem.

Find or estimate bounds of algorithmic complexity or limits of practical solvability of some types of problems.

Registration requirements -

We assume a working knowledge of basic abstract data types, its efficient implementation and application to solve graph problems. Students are assumed to have a passive knowledge of basic proof techniques used in mathematics (proof by induction, by contradiction, constructive) and apart from being able to design a new or modify an existing algorithm, they should be able to analyse its complexity.
