Applied AI with 'oct' on problem 3 to obtain the following invariants:

  For symbol evalspeedSingleSingle0: X_2 - 1 >= 0 /\ X_1 + X_2 - 1 >= 0 /\ -X_1 + X_2 - 1 >= 0 /\ X_1 >= 0

  For symbol evalspeedSingleSingle1: X_2 - 1 >= 0 /\ X_1 + X_2 - 1 >= 0 /\ -X_1 + X_2 - 1 >= 0 /\ X_1 >= 0

  For symbol evalspeedSingleSinglebb1in: X_1 >= 0

  For symbol evalspeedSingleSinglebb2in: X_2 - 1 >= 0 /\ X_1 + X_2 - 1 >= 0 /\ -X_1 + X_2 - 1 >= 0 /\ X_1 >= 0
