Course Description

This lecture revolves around the design and analysis of algorithms. We will discuss the concepts and principles of a selection of the very basic but most commonly used algorithms and datastructures. Topics will include for example: Sorting, searching, hashing, search-trees, (priority-)queues and graph algorithms (like shortest paths, spanning trees, breadth-first- and depth-first-searches).

Exam

  • Type of exam: The exam will probably be oral.
  • Date: TBD
  • Duration: approx. 20 minutes.
