(0)
Obligation:
Rules:
f1_0_main_Load(arg1, arg2) -> f156_0_main_LE(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg2 - 1 && 0 <= arg1P - 1 && -1 <= arg2P - 1
f156_0_main_LE(x, x1) -> f156_0_main_LE(x2, x3) :|: x + x1 = x3 && x = x2 && -1 <= x1 - 1 && 0 <= x - 1 && x1 <= x - 1
__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) -> f156_0_main_LE(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg2 - 1 && 0 <= arg1P - 1 && -1 <= arg2P - 1

__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) -> f156_0_main_LE(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg2 - 1 && 0 <= arg1P - 1 && -1 <= arg2P - 1
(2) f156_0_main_LE(x, x1) -> f156_0_main_LE(x2, x3) :|: x + x1 = x3 && x = x2 && -1 <= x1 - 1 && 0 <= x - 1 && x1 <= x - 1
(3) __init(x4, x5) -> f1_0_main_Load(x6, x7) :|: 0 <= 0

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

This digraph is fully evaluated!
