Group of Algorithms, Cryptography and Computational Logic
 

The group of algorithms, cryptography and computational logic aims at studying notions of computation in order to find solutions and develop efficient algorithms for fundamental problems that arise in applications of computer science. The solutions sought are generic, i.e. independent of particular software or hardware, and rely on mathematical foundations. The group's teaching and research activities are supported by the lab of algorithms, cryptography and computational logic.

The research interests of the group's members are in theoretical informatics, covering diverse areas like computability theory, computational complexity, computational logic, algorithms, data structures, information theory, coding theory, cryptography, cryptanalysis, and computational geometry. Apart from their scientific interest due to their important applications, they also have noticeable overlapping research areas.
