Sound and Complete Witnesses for Template-based Verification of LTL Properties on Polynomial Programs
Krishnendu Chatterjee, Amir Kafshdar Goharshady, Ehsan Kafshdar Goharshady +2
We study the classical problem of verifying programs with respect to formal specifications given in the linear temporal logic (LTL). We first present novel sound and complete witne…
