Parameterized Verification of Quantum Circuits (Technical Report)
Parosh Aziz Abdulla, Yu-Fang Chen, Michal Hečko +4
We present the first fully automatic framework for verifying relational properties of parameterized quantum programs, i.e., a program that, given an input size, generates a corresp…
Negated String Containment is Decidable (Technical Report)
Vojtěch Havlena, Michal Hečko, Lukáš Holík +1
We provide a positive answer to a long-standing open question of the decidability of the not-contains string predicate. Not-contains is practically relevant, for instance in symbol…
A Uniform Framework for Handling Position Constraints in String Solving (Technical Report)
Yu-Fang Chen, Vojtěch Havlena, Michal Hečko +2
We introduce a novel decision procedure for solving the class of position string constraints, which includes string disequalities, not-prefixof, not-suffixof, strat, and not-str…
Algebraic Reasoning Meets Automata in Solving Linear Integer Arithmetic (Technical Report)
Peter Habermehl, Vojtěch Havlena, Michal Hečko +2
We present a new angle on solving quantified linear integer arithmetic based on combining the automata-based approach, where numbers are understood as bitvectors, with ideas from (…
