Loopus

A Tool for Computing Symbolic Bounds on Loops in C Programs

The current version of Loopus is available as binary (64 bit binary for Linux) or source code. Installation instructions can be found in the file INSTALL which is located in the archive. The file README shows how to run loopus.

Welcome Georg Weissenbacher

Georg Weissenbacher, leader of a WWTF funded Vienna Research Group, will start his work in our group on July 2. His project “Heisenbugs: From Detection to Explanation” is applying formal methods to identify hard-to-detect errors in computer systems. See a newspaper article on his work in “Der Standard”.

Uni-Finanzierung als Absurdes Theater (Der Standard)

An sieben Universitäten werden in Österreich Informatik-Studien angeboten, aber mehr als 50 Prozent der Studierenden wählen die TU Wien – über 1000 Studienanfänger jährlich. Der gute Ruf der TU Wien wird zum Fluch für das Studium, denn auf 52 habilitierte Professoren kommen fast 7000 Studierende; ein solches Verhältnis wäre bei anderen international führenden Universitäten undenkbar. […]
