Formale Methoden der Softwareentwicklung
Dozenten | Dr Tadeusz Litak und Christoph Rauch |
Umfang | Vorlesung+Übung, 4 SWS, ECTS-Credits: 7,5 |
The dates are temporary, please consult UniViS for up to date information. As far as I see, at the moment most likely ones are:
V/UE; 4 SWS; ECTS: 7,5; Gasthörer; Di, 12:15 – 13:45, 00.152-113; Mi, 16:00 – 17:30 (we start 15 mins earlier, at participants’ request!)
Contrary to original plans, Priv. Doz. Milius will not be giving this lecture. The change of the main lecturer to dr Litak entails as least two important changes:
-
The lecture will be given in English
-
Dafny, which appeared in the original course description, will be replaced by another Hoare-reasoning tool, most likely based on separation logic. Details will follow.
Lecture slides
-
Slides of Lecture 1, Oct 13 (password protected)
-
Slides of Lecture 2, Oct 21 (password protected)
-
From lecture 3 on, lectures are given entirely on blackboard, so you can only rely on your notes for this.
-
However, I had some introductory slides used in lecture 9 on the frame problem and reasoning about shared mutable data structures. Available freely, without password.
The password for the first two items was announced at the October 28 lecture. If you still need it, email me.
