(0)
Obligation:
Rules:
f1_0_main_Load(arg1, arg2) -> f145_0_main_LE(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg1P - 1 && -1 <= arg2 - 1 && -1 <= arg2P - 1
f145_0_main_LE(x, x1) -> f145_0_main_LE(x2, x3) :|: x1 + 1 = x3 && x = x2 && 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) -> f145_0_main_LE(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg1P - 1 && -1 <= arg2 - 1 && -1 <= arg2P - 1
f145_0_main_LE(x, x1) -> f145_0_main_LE(x2, x3) :|: x1 + 1 = x3 && x = x2 && x1 <= x - 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) -> f145_0_main_LE(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg1P - 1 && -1 <= arg2 - 1 && -1 <= arg2P - 1
(2) f145_0_main_LE(x, x1) -> f145_0_main_LE(x2, x3) :|: x1 + 1 = x3 && x = x2 && x1 <= x - 1
(3) __init(x4, x5) -> f1_0_main_Load(x6, x7) :|: 0 <= 0

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

This digraph is fully evaluated!

Termination digraph:
Nodes:
(1) f145_0_main_LE(x, x1) -> f145_0_main_LE(x2, x3) :|: x1 + 1 = x3 && x = x2 && x1 <= x - 1

Arcs:
(1) -> (1)

This digraph is fully evaluated!

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

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

(6)
Obligation:
Rules:
f145_0_main_LE(x2:0, x1:0) -> f145_0_main_LE(x2:0, x1:0 + 1) :|: x2:0 - 1 >= x1:0

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

(7) TempFilterProof (SOUND)
Used the following sort dictionary for filtering: 
f145_0_main_LE(INTEGER, INTEGER)
Replaced non-predefined constructor symbols by 0.
----------------------------------------

(8)
Obligation:
Rules:
f145_0_main_LE(x2:0, x1:0) -> f145_0_main_LE(x2:0, c) :|: c = x1:0 + 1 && x2:0 - 1 >= x1:0

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

(9) PolynomialOrderProcessor (EQUIVALENT)
Found the following polynomial interpretation:
[f145_0_main_LE(x, x1)] = x - x1

The following rules are decreasing:
f145_0_main_LE(x2:0, x1:0) -> f145_0_main_LE(x2:0, c) :|: c = x1:0 + 1 && x2:0 - 1 >= x1:0
The following rules are bounded:
f145_0_main_LE(x2:0, x1:0) -> f145_0_main_LE(x2:0, c) :|: c = x1:0 + 1 && x2:0 - 1 >= x1:0

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