Rules:
f1_0_main_Load(arg1, arg2) -> f31_0_loop_InvokeMethod(arg1P, arg2P) :|: arg2 = arg1P && -1 <= arg2 - 1 && 0 <= arg1 - 1
f31_0_loop_InvokeMethod(x, x1) -> f31_0_loop_InvokeMethod(x2, x3) :|: x = x2
__init(x4, x5) -> f1_0_main_Load(x6, x7) :|: 0 <= 0
Start term: __init(arg1, arg2)

----------------------------------------

(1) IRSFormatTransformerProof (EQUIVALENT)
Reformatted IRS to match normalized format (transformed away non-linear left-hand sides, !=, / and %).
----------------------------------------

(2)
Obligation:
Rules:
f1_0_main_Load(arg1, arg2) -> f31_0_loop_InvokeMethod(arg1P, arg2P) :|: arg2 = arg1P && -1 <= arg2 - 1 && 0 <= arg1 - 1
f31_0_loop_InvokeMethod(x, x1) -> f31_0_loop_InvokeMethod(x2, x3) :|: x = x2
__init(x4, x5) -> f1_0_main_Load(x6, x7) :|: 0 <= 0
Start term: __init(arg1, arg2)

----------------------------------------

(3) IRSwTTerminationDigraphProof (EQUIVALENT)
Constructed termination digraph!
Nodes:
(1) f1_0_main_Load(arg1, arg2) -> f31_0_loop_InvokeMethod(arg1P, arg2P) :|: arg2 = arg1P && -1 <= arg2 - 1 && 0 <= arg1 - 1
(2) f31_0_loop_InvokeMethod(x, x1) -> f31_0_loop_InvokeMethod(x2, x3) :|: x = x2
(3) __init(x4, x5) -> f1_0_main_Load(x6, x7) :|: 0 <= 0

Arcs:
(1) -> (2)
(2) -> (2)
(3) -> (1)

This digraph is fully evaluated!
----------------------------------------

(4)
Obligation:

Termination digraph:
Nodes:
(1) f31_0_loop_InvokeMethod(x, x1) -> f31_0_loop_InvokeMethod(x2, x3) :|: x = x2

Arcs:
(1) -> (1)

This digraph is fully evaluated!

----------------------------------------

(5) IntTRSCompressionProof (EQUIVALENT)
Compressed rules.
----------------------------------------

(6)
Obligation:
Rules:
f31_0_loop_InvokeMethod(x2:0, x1:0) -> f31_0_loop_InvokeMethod(x2:0, x3:0) :|: TRUE

----------------------------------------

(7) FilterProof (EQUIVALENT)
Used the following sort dictionary for filtering: 
f31_0_loop_InvokeMethod(VARIABLE, VARIABLE)
Replaced non-predefined constructor symbols by 0.
----------------------------------------

(8)
Obligation:
Rules:
f31_0_loop_InvokeMethod(x2:0, x1:0) -> f31_0_loop_InvokeMethod(x2:0, x3:0) :|: TRUE

----------------------------------------

(9) IntTRSNonPeriodicNontermProof (COMPLETE)
Normalized system to the following form:
f(pc, x2:0, x1:0) -> f(1, x2:0, x3:0) :|: pc = 1 && TRUE
Proved unsatisfiability of the following formula, indicating that the system is never left after entering:
(((run2_0 = ((1 * 1)) and run2_1 = ((run1_1 * 1)) and run2_2 = ((run1_3 * 1))) and (((run1_0 * 1)) = ((1 * 1)) and T)) and !(((run2_0 * 1)) = ((1 * 1)) and T))
Proved satisfiability of the following formula, indicating that the system is entered at least once:
((run2_0 = ((1 * 1)) and run2_1 = ((run1_1 * 1)) and run2_2 = ((run1_3 * 1))) and (((run1_0 * 1)) = ((1 * 1)) and T))

----------------------------------------

(10)
NO
