In this seminar, we introduce some state-of-the-art techniques that help programmers check the correctness of their developed software systems. Examples of correctness properties include: the program does not crash (eg, through null pointer exceptions), it does not contain security vulnerabilities (such as buffer overflows), and it calculates the correct result. We focus on lightweight techniques that are fully automatic, easy-to-use, and do not require much user-provided assistance, and thus present a potential to be applied to real-world industrial software.

Topics include:

  • Automatic debugging tools 
  • Non-termination detection   
  • Decision procedures for bit-vectors, arrays, and integers   
  • Software bounded model checking   
  • Feedback-driven program checking   
  • Information flow analysis


  • There is no official first class for this seminar. The students can join any time they like, but they are responsible for preparing their presentations and written reports according to the timeline explained below.    
  • Interested students must pick a topic from the following list and inform the lecturers by email. The corresponding lecturer will then set up a meeting with the student to discuss the topic further.   
  • Each student has to give a presentation on his/her chosen topic at the end of the semester (08.02.2013). Talks will be in English, and should fit in a 30 minute time slot + 10 minutes discussion time.   
  • Each student should have at least 2 meetings with the supervisor. One in early December, and one 2 weeks before the talk (mid January).   
  • Each student should submit a write-up (10-12 pages) at the end of the semester (11.02.2013 at the latest). A short summary should be submitted at the second meeting with the supervisor.
