STLSat---An Improved Tableau for Satisfiability Checking of Signal Temporal Logic Formulas

Marco Zamponi, Florian Lammel, Ezio Bartocci +1

Signal Temporal Logic (STL) is a formalism used to describe temporal properties of real-valued signals in cyber-physical systems. In mission- and safety-critical domains, specifica…

Robust Classification in ML: A Topological Semantics Approach

Dominik Pichler, Mirko Tagliaferri

Robust classification is commonly understood as the stability of a classifier under small perturbations (often adversarial) of input data. In this paper, we propose a logical frame…

Streamliners for Answer Set Programming

Florentina Voboril, Martin Gebser, Stefan Szeider +1

Streamliner constraints reduce the search space of combinatorial problems by ruling out portions of the solution space. We adapt the StreamLLM approach, which uses Large Language M…

Finding Connections via Satisfiability Solving

Clemens Eisenhofer, Michael Rawson, Laura Kovács

Commonly used proof strategies by automated reasoners organise proof search either by ordering-based saturation or by reducing goals to subgoals. In this paper, we combine these tw…

On Solving String Equations via Powers and Parikh Images

Clemens Eisenhofer, Theodor Seiser, Nikolaj S. Bjørner +1

We present a new approach for solving string equations as extensions of Nielsen transformations. Key to our work are the combination of three techniques: a power operator for strin…

Constraint Learning for Non-confluent Proof Search

Michael Rawson, Clemens Eisenhofer, Laura Kovács

Proof search in non-confluent tableau calculi, such as the connection tableau calculus, suffers from excess backtracking, but simple restrictions on backtracking are incomplete. We…
