Knowledge obtained : [(AND p1 p0), (X (NOT (AND (NOT p0) (NOT p1)))), (X (NOT (AND p0 (NOT p1)))), (X (AND p0 p1)), (X p0), (X p1), (X (X (NOT (AND (NOT p0) p1)))), (X (X (NOT (AND (NOT p0) (NOT p1))))), (X (X (NOT (AND p0 (NOT p1))))), (X (X (AND p0 p1))), (X (X p0)), (X (X p1)), (F (OR (G p1) (G (NOT p1))))]
False Knowledge obtained : []
Knowledge sufficient to adopt a stutter insensitive property.
Knowledge based reduction with 13 factoid took 137 ms. Reduced automaton from 5 states, 11 edges and 2 AP (stutter sensitive) to 4 states, 10 edges and 2 AP (stutter insensitive).
