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

Start term: __init(arg1, arg2, arg3)

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

(3) IRSwTTerminationDigraphProof (EQUIVALENT)
Constructed termination digraph!
Nodes:
(1) f1_0_main_ConstantStackPush(arg1, arg2, arg3) -> f66_0_main_GE(arg1P, arg2P, arg3P) :|: arg2 = arg3P && 0 = arg2P && 0 <= arg1P - 1 && 0 <= arg1 - 1 && -1 <= arg2 - 1 && arg1P <= arg1

(3) __init(x6, x7, x8) -> f1_0_main_ConstantStackPush(x9, x10, x11) :|: 0 <= 0

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

This digraph is fully evaluated!

Termination digraph:
Nodes:
(1) f66_0_main_GE(x, x1, x2) -> f66_0_main_GE(x3, x4, x5) :|: x2 = x5 && x1 + 1 = x4 && 0 <= x3 - 1 && 0 <= x - 1 && x3 <= x && -1 <= x2 - 1 && x1 <= x2 - 1

Arcs:
(1) -> (1)

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

(6)
Obligation:
Rules:
f66_0_main_GE(x:0, x1:0, x2:0) -> f66_0_main_GE(x3:0, x1:0 + 1, x2:0) :|: x2:0 > -1 && x2:0 - 1 >= x1:0 && x:0 >= x3:0 && x3:0 > 0 && x:0 > 0

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

(7) TempFilterProof (SOUND)
Used the following sort dictionary for filtering: 
f66_0_main_GE(INTEGER, INTEGER, INTEGER)
Replaced non-predefined constructor symbols by 0.
----------------------------------------

(8)
Obligation:
Rules:
f66_0_main_GE(x:0, x1:0, x2:0) -> f66_0_main_GE(x3:0, c, x2:0) :|: c = x1:0 + 1 && (x2:0 > -1 && x2:0 - 1 >= x1:0 && x:0 >= x3:0 && x3:0 > 0 && x:0 > 0)

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

(9) RankingReductionPairProof (EQUIVALENT)
Interpretation:
[ f66_0_main_GE ] = f66_0_main_GE_3 + -1*f66_0_main_GE_2

The following rules are decreasing:
f66_0_main_GE(x:0, x1:0, x2:0) -> f66_0_main_GE(x3:0, c, x2:0) :|: c = x1:0 + 1 && (x2:0 > -1 && x2:0 - 1 >= x1:0 && x:0 >= x3:0 && x3:0 > 0 && x:0 > 0)

The following rules are bounded:
f66_0_main_GE(x:0, x1:0, x2:0) -> f66_0_main_GE(x3:0, c, x2:0) :|: c = x1:0 + 1 && (x2:0 > -1 && x2:0 - 1 >= x1:0 && x:0 >= x3:0 && x3:0 > 0 && x:0 > 0)
