 Learning objectives: 

  Familiarity with graphs and graph algorithms with their complexities.  Description: 

  This course discusses graph representations and graphs algorithms for searching (depthfirst search, breadthfirst search), topological sorting, graph components and strongly connected components, trees and minimal spanning trees, singlesource and allpairs shortest paths, maximal flows and minimal cuts, maximal bipartite matching, Euler graphs, and graph coloring. The principles and complexities of all presented algorithms are discussed.  Knowledge and skills required for the course: 

  Foundations in discrete mathematics and algorithmic thinking.  Learning outcomes and competences: 

  Fundamental ability to construct an algorithm for a graph problem and to analyze its time and space complexity.  Syllabus of lectures: 


 Introduction, algorithmic complexity, basic notions and graph representations.
 Graph searching, depthfirst search, breadthfirst search.
 Topological sort, acyclic graphs.

 Controlled instruction: 

  A written midterm exam, an evaluation of projects, and a final exam. The minimal number of points which can be obtained from the final exam is 25. Otherwise, no points will be assigned to a student.  Progress assessment: 

  A midterm exam evaluation (max. 15 points) and an evaluation of projects (max. 25 points).
