Subject aims expressed by acquired skills and competences

Each student is supposed to - analyze real life problems - express them as a graph theory problem - solve the problem using graph theory methods - give an interpretation of the theoretical results in the terms of the original problems At the same time he should decide what are the limits of an ideal theoretical solution in contrast to the real situation.

Summary

The course covers both basic and advanced topics of Graph Theory, often overlapping with other branches of mathematics (algebra, combinatorics). A mandatory part of the course is one or sometimes two projects focused on real life problems that are solved using methods of graph theory.

Compulsory literature:

J. Matoušek, J. Nešetřil, Chapters in Discrete Mathematics, Karolinum Praha (2010).

Recommended literature:

D. B. West, Introduction to graph theory, Prentice-Hall, Upper Saddle River NJ, (2019), ISBN 9780131437371.

Way of continuous check of knowledge in the course of semester

During the semester each student prepares one or two projects. Topic of each project is chosen among topics presented in the lecture. The sumbission date and all assignments are available on the instructor webpage or in the university electronic information system. (Each student has to register for a topic.) For a pass it is necessary to have at least one project graded for at least 10 points.
