Audience

This advanced course addresses Bachelor and Master students in Computer Science, Bioinformatics, CuK or Computerlinguistics. Background in probability theory and the module Verification are of advantage but not mandatory.

Objectives

Quantitative model checking is concerned with quantities (mostly probabilities) within systems exhibiting random behaviour. Such systems include networked, embedded, or biological systems. Their underlying semantics are usually discrete-time and/or continuous-time Markov chains, possibly extended with nondeterminism. On the respective models, quantitative properties of interest can be verified. The properties can be specified, e.g., by PCTL or LTL for discrete-time models, and CSL for continuous-time models. This course aims to cover both the model construction and the verification techniques for these systems.

Credits: 6 ECTS points (2 hours of lecture, 2 hours of tutorials, and some exercices every week)

When and where?

Lectures: every Tuesday 10 - 12 in the seminar room 016 in E1 3, starting on October 21, 2014.
Tutorials: every Thursday 10 - 12 in the room 528 in E1 3, starting on November 6, 2014

Grading

There will be a final written exam: 

  • Exam: Tuesday February 24, 10:15 AM, E1 3 016
  • Re-exam: Tuesday March 24, 10:15 AM, E1 3 016

Having at least 50% points for both theoretical and practical exercises is required for admission to the final exam. Your current point status will be made available in dCMS.
