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

(16)
Obligation:
Rules:
l2(x:0, x1:0, x2:0, x33:0, x10:0, x5:0) -> l2(x10:0, 3 + x5:0, x2:0, x33:0, x10:0, 3 + x5:0) :|: x5:0 < 18

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

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

   l2(x1, x2, x3, x4, x5, x6) -> l2(x6)

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

(18)
Obligation:
Rules:
l2(x5:0) -> l2(3 + x5:0) :|: x5:0 < 18

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

(19) TempFilterProof (SOUND)
Used the following sort dictionary for filtering: 
l2(INTEGER)
Replaced non-predefined constructor symbols by 0.
----------------------------------------

(20)
Obligation:
Rules:
l2(x5:0) -> l2(c) :|: c = 3 + x5:0 && x5:0 < 18

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

(21) PolynomialOrderProcessor (EQUIVALENT)
Found the following polynomial interpretation:
[l2(x)] = 17 - x

The following rules are decreasing:
l2(x5:0) -> l2(c) :|: c = 3 + x5:0 && x5:0 < 18
The following rules are bounded:
l2(x5:0) -> l2(c) :|: c = 3 + x5:0 && x5:0 < 18

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

(22)
YES
