Logic and Programming
research group at
Main research line:
Methods and foundations of logic-based tools for dealing with hard
plays a fundamental role in many computer science areas:
databases, programming languages, software engineering, verification…
In fact, logic has been called "the calculus of computer science", as
it plays a similar role in computer science to that of calculus in the
physical sciences and traditional engineering disciplines (M. Vardi,
group has done research in automated theorem proving in first-order logic with equality (paramodulation) and in higher-order logic (higher-order
unification). Nowadays the group is interested in propositional satisfiability
(SAT) and SAT modulo theories (SMT) and their applications to solve combinatorial
problems in areas such as planning and scheduling: timetabling, task sequencing in industrial processes, etc.
