Regular Strategies as Proof Tactics for CIRC

Dorel Lucanu, Grigore Roşu, Gheorghe Grigoraş
2008 Electronical Notes in Theoretical Computer Science  
In this paper we prove the correctness of the coinductive prover and show how rewriting strategies, expressed as regular expressions, can be used for specifying proof tactics for CIRC.  ...  We illustrate the strength of the method by defining a proof tactic combining the circular coinduction with a particular form of simplification for proving the equivalence of context-free processes.  ...  The use of regular strategies as proof tactics enlarge the class of problems which can be automatically solved. CIRC implements also the circularity principle for proving properties by induction.  ...

Operational Semantics Based Formal Symbolic Simulation [chapter]

K.G.W. Goossens
1993 Higher Order Logic Theorem Proving and its Applications  
Using a number of small examples, we will then show the how this formal semantics may be used within a proof system as a sophisticated simulation tool.  ...  Tactics may be used to great advantage in this sort of regular reasoning.  ...  A tactic would actually replay or recreate the proof tree, which would be as slow as rerunning the proof. The application of a derived rule, in contrast, is as fast as a primitive rule.  ...

A Deductive Verification Framework for Circuit-building Quantum Programs [article]

Christophe Chareton, Sébastien Bardin, François Bobot, Valentin Perrelle, Benoit Valiron
2020 arXiv   pre-print
We propose Qbricks, the first formal verification environment for circuit-building quantum programs, featuring clear separation between code and proof, parametric specifications and proofs, high degree  ...  As a consequence, no significant quantum algorithm implementation has been currently verified in a scale-invariant manner.  ...  As all expressions in Qbricks-DSL are terminating, one can use regular sets as denotational semantics for the language.  ...

Presumptions in Legal Argumentation

2012 Ratio Juris  
Presumptions come into play in argumentation when the evidence needed to prove or disprove a position is incomplete, allowing the investigation to move forward to meet a standard of proof.  ...  The tactical burden of proof, it can be said, has now shifted to defendant.  ...  Certainly it is not easy at first to clearly grasp the distinction between burden of production and tactical burden of proof, but from the point of view of understanding burden of proof as a concept of  ...

for the language's operational semantics.  ...  We show how the proposed symbolic-execution approach, and the coinductive verification technique based on it, can be seamlessly implemented in language definition frameworks based on rewriting such as  ...  In general, for an element in ν R (or µ R) there may exist more than one proof tree. In [45] games and strategies are used for finding specific proof trees.  ...

The Role of Shared E-Scooter Systems in Urban Sustainability and Resilience during the Covid-19 Mobility Restrictions

Gabriel Dias, Elisabete Arsenio, Paulo Ribeiro
2021 Sustainability  
The success of this mode is also due to new urban mobility strategies and plans, such as the European Sustainable and Smart Mobility Strategy, which relies on non-pollutant modes.  ...  In the case study of Braga, it was found that the city still relies on shared e-scooter modes as a mobility option after the pandemic, also promoting special fares for people to start using the service  ...  Bird (former Circ) and Hive charged €1.00 to unlock the e-scooter and more €0.15 for each minute traveled, but Bird also provided some different charging options, such as €6.00 per 1 h traveled, €10.00  ...
