	Certificate of Non-Termination

	Original rule:
	l0 -> l0 : lt_9^0'=lt_9^post2, (1+x_5^0-y_6^0 <= 0), cost: 1
	New rule:
	l0 -> LoAT_sink : (-1+n >= 0 /\ -1-x_5^0+y_6^0 >= 0), cost: NONTERM

		-1-x_5^0+y_6^0 >= 0 [0]: monotonic increase yields -1-x_5^0+y_6^0 >= 0
		
		Replacement map: {-1-x_5^0+y_6^0 >= 0 -> -1-x_5^0+y_6^0 >= 0}
