CTL (Computation Tree Logic)

Computation Tree Logic (CTL) is a formal language used to specify and reason about how systems behave over time. It models all possible sequences of events and states, representing them as a branching tree. Using CTL, you can express properties like "something good eventually happens" or "something bad never occurs," and verify if a system design meets those properties. It’s commonly used in formal verification to ensure systems (like software or hardware) function correctly under different scenarios, providing a rigorous way to analyze system reliability and safety.
