	Eliminating location f1_0_main_Load by chaining:

	Applied chaining

	First rule:
	__init -> f1_0_main_Load : arg1'=arg1p3, arg2'=arg2p3, T, cost: 1
	Second rule:
	f1_0_main_Load -> f127_0_eq_LE : arg1'=arg1p1, arg2'=arg2p1, (arg1 > 0 /\ 1+arg1p1 > 0 /\ 1+arg2p1 > 0 /\ -1+arg2 > 0), cost: 1
	New rule:
	__init -> f127_0_eq_LE : arg1'=arg1p1, arg2'=arg2p1, (arg1p3 > 0 /\ -1+arg2p3 > 0 /\ 1+arg1p1 > 0 /\ 1+arg2p1 > 0), cost: 1
	
	Applied deletion

	Removed the following rules: 0 2
