문제
I have been learning Verification by model checking recently and I get the following question:
Is the CTL formula $s_{0} \models EG\ AF\ p$ valid in the following model?
I think it is incorrect because there is a deadlock or infinite loop about $s_0$ after the state is starting from $s_0$, which make it invalid under $EG\ AF\ $ condition.
Am I correct? How can I prove it (or give a counterexample)?
