PROTHEO Research team
Constraints, automatic deduction and software properties proofs
- Leader : Claude Kirchner
- Research center(s) : CRI Nancy - Grand Est
- Field : Symbolic systems
- Theme : Reliability and safety of software
The PROTHEO project-team aims at designing and implementing tools for program specification and verification.
We are working on an environment for prototyping such tools, on theorem provers specialised in proofs by induction and equational first-order proofs, on proof techniques involving constraints and rewrite rules. The project has three strongly connected research themes: constraint solving, mechanised deduction with rewrite rules and strategies, and theorem proving.
- Constraint solving.
- Constraint satisfiability on symbolic and numerical domains.
- Collaboration of constraint solvers.
- Constraint satisfaction techniques.
- Mechanised deduction with rewrite rules and strategies.
- Strategy language for constraint solvers and theorem provers.
- Non-deterministic computations.
- Compilation of rewriting and strategies.
- Properties of confluence, termination, modularity.
- Theorem proving.
- Automated deduction with constraints.
- Proofs by induction.
- Observational proofs.
- Proofs of program properties.
