Course objectives
This is an introductory course in graph theory.
Learning outcomes
After passing the course, students will be able to: use the basic notions of graph theory; define and understand basic properties of graphs, in particular, edge connectivity, vertex connectivity, planarity and chromatic number; explain and apply the most important results of graph theory; solve simple graph problems using standard effective algorithms.
Syllabus
