Diese Lehrveranstaltung soll Studierenden die grundlegenden theoretischen und praktischen Aspekte der Algorithmentechnik vermitteln. Es werden generelle Methoden zum Entwurf und der Analyse von Algorithmen für grundlegende algorithmische Probleme vermittelt sowie die Grundzüge allgemeiner algorithmischer Methoden wie Approximationsalgorithmen, Lineare Programmierung, Randomisierte Algorithmen, Parallele Algorithmen und parametrisierte Algorithmen behandelt.
