Ctl semantics
WebFeb 1, 2024 · Therefore, a distinctive feature of ℒ𝒫-CTL* semantics is a certain synchronization of the parameters of temporal operators (their interpretation is determined by the sequence of input signals) and the truth values of the basic predicates (they depend on the sequence of output actions). One may say that the semantics of our logic is … WebBy the CTL semantics you know that $p$ satisfies the path formula $\big(a \textsf{U} (b \land \forall \square a)\big)$. It will have a prefix labeled by $a$ and the state $s$ at the …

CTL has been extended with second-order quantification $${\displaystyle \exists p}$$ and $${\displaystyle \forall p}$$ to quantified computational tree logic (QCTL). There are two semantics: the tree semantics. We label nodes of the computation tree. QCTL* = QCTL = MSO over trees.
