(5) IntTRSCompressionProof (EQUIVALENT)
Compressed rules.

Rules:
l0(oldX0HAT0:0, oldX1HAT0:0, oldX0HATpost:0) -> l0(1 + oldX0HATpost:0, oldX1HAT0:0, 1 + oldX0HATpost:0) :|: oldX0HATpost:0 < 10

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

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

   l0(x1, x2, x3) -> l0(x3)

(8)
Obligation:
Rules:
l0(oldX0HATpost:0) -> l0(1 + oldX0HATpost:0) :|: oldX0HATpost:0 < 10

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

(9) TempFilterProof (SOUND)
Used the following sort dictionary for filtering: 
l0(INTEGER)
Replaced non-predefined constructor symbols by 0.
----------------------------------------

(10)
Obligation:
Rules:
l0(oldX0HATpost:0) -> l0(c) :|: c = 1 + oldX0HATpost:0 && oldX0HATpost:0 < 10

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

(11) RankingReductionPairProof (EQUIVALENT)
Interpretation:
[ l0 ] = -1*l0_1

The following rules are decreasing:
l0(oldX0HATpost:0) -> l0(c) :|: c = 1 + oldX0HATpost:0 && oldX0HATpost:0 < 10

The following rules are bounded:
l0(oldX0HATpost:0) -> l0(c) :|: c = 1 + oldX0HATpost:0 && oldX0HATpost:0 < 10
