Résumé:
Software engineering, automated reasoning, rule-based programming or
specifications often use rewriting systems for which termination,
among other properties, may have to be ensured.
This paper presents the approach developed in Project A3PAT to
discover and moreover certify, with full automation, termination
proofs for term rewriting systems.
It consists of two developments: the Coccinelle library formalises
numerous rewriting techniques and termination criteria for the Coq
proof assistant; the CiME3 rewriting tool translates termination
proofs (discovered by itself or other tools) into traces that are
certified by Coq assisted by Coccinelle.
The abstraction level of our formalisation allowed us to weaken
premises of some theorems known in the literature, thus yielding new
termination criteria, such as an extension of the powerful subterm
criterion (for which we propose the first full Coq formalisation).
Techniques employed in CiME3 also improve on previous works on
formalisation and analysis of dependency graphs.
