Course detail

Graph Algorithms

FSI-9GRAAcad. year: 2023/2024

The course focuses on graph theory and familiarises students with fundamental terms and algorithms. It deals with the following topics: Graph representation. Time complexity of algorithms. Data structures (binary heap, disjoint sets, ...). Eulearian trails, Hamiltonian paths. Breadth-first searching, depth-first searching, backtracking, branch and bound method. Connectivity and reachability. Shortest path problems (Dijkstra's algorithm, Floyd-Warshall algorithm). Network graphs. Trees, spanning tree problem, Steiner tree problems. Fundamentals of computational geometry - visibility graphs, Voronoi diagrams, Delaunay triangulation. Network flows. Graph colouring. Graph matching.

Mode of study

Not applicable.

Entry knowledge

Successful completion of the course "Graph Algorithms" is conditional on basic knowledge of set theory, combinatorics and operations research.

Rules for evaluation and completion of the course

The course-unit credit is awarded on condition of having described or implemented a nontrivial graph algorithm. The exam has a written form and tests students’ knowledge of terms and fundamental algorithms.


The course aims to acquaint the students with the graph theory and graph-based algorithms that extend the knowledge acquired in subjects courses focused on artificial intelligence, operations research, project management and computer networks and are commonly used to solve problems in engineering and other areas.

The students will be made familiar with the basics of the graph theory and graph algorithms. This will provide them with tools for using graphs to model various practical problems, which may then be solved by using the graph algorithms.
