Midterm 1 time change, date remains

Written on 15.04.25 (last change on 15.04.25) by Anran Wang

Dear participants of Verification,

Due to the large number of registrations on CMS and the limited capacity of HS003, we have to move midterm 1 to 14-16 o’clock (still on 20.05) to Math lecture hall 1 at E2 5.

Dear participants, 

The tutorials have been assigned. If you have any problem, please contact us through discord or via email. 

Alternative tutorial replacing the first Friday tutorial

(This does not concern participants of the Thursday tutorial.)

Due to public holiday (Karfreitag) on 18. April, there will be no tutorial on that Friday. 
However, we offer a replacement tutorial on 17. April, starting from 10:00 c.t. at seminar room E1 3 107 (on the first floor of the same building where the lecture takes place). 
If you can not join in this time, we will provide sample solutions to exercise sheet 0, and will be available for questions. 

All subsequent Friday tutorials will take place in the regular time and place.

Lecturer   Prof. Benjamin Kaminski
TA   Tobias Gürtler, Lucas Kehrer, Anran Wang

 

Introduction

Compute systems are everywhere, including in critical scenarios where human lives are at stake (airplanes, hospitals, nuclear power plants, etc.). It is paramount that such systems are safe. But what does "safe" even mean?

In this lecture, we will explore various logics for specifying and techniques for proving with mathematical rigor that systems are safe. Time permitting, we will also peek into methods for reasoning about quantitative properties of probabilistic systems.

Topics which we will cover include:

  • Model checking
  • Linear temporal logic (LTL)
  • Computation tree logic (CTL)
  • Hoare logic
  • Weakest preconditions / predicate transformers
  • k-induction
  • Probabilistic verification

 

Structure

This course consists of two weekly lectures and one tutorial. The lectures take place Mondays from 10:00 m.c.t. – 12:00, and Tuesdays from 12:00 c.t. – 14:00 (see below) at E1 3, Lecture Hall III (0.03.1) starting from 8. April. 

For the tutorial, we offer two dates: Either Thursdays or Fridays 10:00 – 12:00 in seminar room SR 014 (Thursdays) or SR 015 (Fridays) both in building E1 3 starting from 17th April.

There will be two midterm exams taking place during the lecture dates. Passing the midterms is required to be admitted to the final exam. Details announced in the first lecture. Homework is not required to be admitted to the exam.

There will be weekly homework, which consists two parts: Part 1 (basic) and Part 2 (advanced). Homework submission is voluntary. Upon submission, Part 1 will be corrected and returned to you. Sample solutions will be provided for Part 2. In the tutorial, we will discuss last week's homework and answer questions. 

Check the timetable for time and place of lectures, tutorials, midterms, and final exams.
