CS5030 - Automated Program Verification

Course Data :

Description: Automated Verification of programs has often been called the holy grail of computer science. While undecidable in general, over the years, a number of elegant techniques have been developed to solve this problem for several useful classes of programs. In today's world, where the boundary between safety-critical and non-safety-critical applications has become vanishingly thin and the volume and complexity of software has become staggeringly large, Automated Verification has started to gain more importance. In this course, we will go through a wide spectrum of techniques used in the domain of Automated Verification. The course will emphasize on both theory and practice, with hands-on experience of some of the tools used in this domain. In addition, the course will also involve reading the latest research papers in the area.
