The meaning of operators in AAFA.

Operator	Explanation
IN(𝑠,ℎ)	Satisfied at time 𝑡^′ in which (𝑠(𝑡^′)≤ℎ))
IN[time](𝑠,ℎ)	Satisfied at time 𝑡^′((𝑡^′∈time) in which (𝑠(𝑡^′)≤ℎ))
FIN(𝑓1,𝑓2,FFT(𝑠),𝛽)	Satisfied if ∃𝑓∈[𝑓1,𝑓2]⇒FFT(𝑠)(𝑓)≤𝛼
GFIN(𝑓1,𝑓2,FFT(𝑠),𝛽)	Satisfied if ∀𝑓∈[𝑓1,𝑓2]⇒FFT(𝑠)(𝑓)≤𝛼
𝐺{[𝑡]}(ℎ),𝐹{[𝑡]}(ℎ),; ℎ∈AAFA+A	Satisfied if the formula ℎ holds always or at least once during simulation, respectively
