<strong>Definition:</strong>
A propositional, branching-time temporal logic for which formulas can be checked in <a href="linear.html" tppabs="http://hissa.nist.gov/dads/HTML/linear.html"><em>linear</em></a> time. It stands for Computation Tree Logic.
<P><em>Note:
CTL differs from CTL* in that in CTL path quantifiers (E and A) always appear with temporal operators (F, G, X, U, etc.). Therefore CTL formulas are <em>state</em> formulas.</em>
