Testing for reachability in the complexity graph removes the following transitions from problem 1:
	eval_cousot9_bb2_in(Ar_0, Ar_1, Ar_2, Ar_3) -> Com_1(eval_cousot9_bb1_in(Ar_1, Ar_1, Ar_2, Ar_3)) [ Ar_0 > 0 /\ Ar_0 <= 0 ]

Applied AI with 'oct' on problem 4 to obtain the following invariants:
  For symbol eval_cousot9_bb1_in: X_2 - X_3 >= 0
  For symbol eval_cousot9_bb2_in: X_2 - X_3 >= 0 /\ X_3 - 1 >= 0 /\ X_2 + X_3 - 2 >= 0 /\ X_2 - 1 >= 0
