(0)
Obligation:
Rules:
f1_0_main_Load(arg1, arg2) -> f79_0_overflow_GT(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg1P - 1 && -1 <= arg2 - 1
f79_0_overflow_GT(x, x1) -> f79_0_overflow_GT(x2, x3) :|: x + 1 = x2 && x <= 2147483647
__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) -> f79_0_overflow_GT(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg1P - 1 && -1 <= arg2 - 1
f79_0_overflow_GT(x, x1) -> f79_0_overflow_GT(x2, x3) :|: x + 1 = x2 && x <= 2147483647
__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) -> f79_0_overflow_GT(arg1P, arg2P) :|: 0 <= arg1 - 1 && -1 <= arg1P - 1 && -1 <= arg2 - 1
(2) f79_0_overflow_GT(x, x1) -> f79_0_overflow_GT(x2, x3) :|: x + 1 = x2 && x <= 2147483647
(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) f79_0_overflow_GT(x, x1) -> f79_0_overflow_GT(x2, x3) :|: x + 1 = x2 && x <= 2147483647

Arcs:
(1) -> (1)

This digraph is fully evaluated!

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

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

(6)
Obligation:
Rules:
f79_0_overflow_GT(x:0, x1:0) -> f79_0_overflow_GT(x:0 + 1, x3:0) :|: x:0 < 2147483648

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

(7) IntTRSUnneededArgumentFilterProof (EQUIVALENT)
Some arguments are removed because they cannot influence termination. We removed arguments according to the following replacements:

   f79_0_overflow_GT(x1, x2) -> f79_0_overflow_GT(x1)

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

(8)
Obligation:
Rules:
f79_0_overflow_GT(x:0) -> f79_0_overflow_GT(x:0 + 1) :|: x:0 < 2147483648

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

(9) TempFilterProof (SOUND)
Used the following sort dictionary for filtering: 
f79_0_overflow_GT(INTEGER)
Replaced non-predefined constructor symbols by 0.
----------------------------------------

(10)
Obligation:
Rules:
f79_0_overflow_GT(x:0) -> f79_0_overflow_GT(c) :|: c = x:0 + 1 && x:0 < 2147483648

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

(11) PolynomialOrderProcessor (EQUIVALENT)
Found the following polynomial interpretation:
[f79_0_overflow_GT(x)] = 2147483647 - x

The following rules are decreasing:
f79_0_overflow_GT(x:0) -> f79_0_overflow_GT(c) :|: c = x:0 + 1 && x:0 < 2147483648
The following rules are bounded:
f79_0_overflow_GT(x:0) -> f79_0_overflow_GT(c) :|: c = x:0 + 1 && x:0 < 2147483648

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