	Eliminating location f1_0_main_Load by chaining:

	Applied chaining

	First rule:
	__init -> f1_0_main_Load : arg1'=arg1p3, arg2'=arg2p3, arg3'=arg3p3, arg4'=arg4p3, T, cost: 1
	Second rule:

	New rule:
	__init -> f587_0_main_LT : arg1'=arg1p1, arg2'=arg2p1, arg3'=arg3p1, arg4'=arg4p1, (1+arg2p3 > 0 /\ 1+arg1p1 > 0 /\ -arg3p1+arg1p1-arg2p1 == 0 /\ 1+arg2p1 > 0 /\ arg1p3 > 0 /\ 2-arg4p1 == 0), cost: 1
	
	Applied deletion
