Q is empty.
We have to consider all minimal (P,Q,R)-chains.

(19) UsableRulesProof (EQUIVALENT transformation)

We can use the usable rules and reduction pair processor [LPAR04] with the Ce-compatible extension of the polynomial order that maps every function symbol to the sum of its arguments. Then, we can delete all non-usable rules [FROCOS05] from R.

(20) Obligation:

Q DP problem:
The TRS P consists of the following rules:

11(3(0(x))) → 11(x)
11(1(0(x))) → 11(x)
11(4(2(0(x)))) → 11(x)
11(3(0(3(x)))) → 11(x)
11(4(2(4(0(x))))) → 11(x)
11(4(1(0(3(x))))) → 11(1(0(2(3(4(x))))))

The TRS R consists of the following rules:

3(4(5(4(0(x))))) → 3(4(4(0(5(2(x))))))

Q is empty.
We have to consider all minimal (P,Q,R)-chains.

(21) MRRProof (EQUIVALENT transformation)

By using the rule removal processor [LPAR04] with the following ordering, at least one Dependency Pair or term rewrite system rule of this QDP problem can be strictly oriented.
Strictly oriented dependency pairs:

11(3(0(x))) → 11(x)
11(1(0(x))) → 11(x)
11(4(2(0(x)))) → 11(x)
11(3(0(3(x)))) → 11(x)
11(4(2(4(0(x))))) → 11(x)
11(4(1(0(3(x))))) → 11(1(0(2(3(4(x))))))

Strictly oriented rules of the TRS R:

3(4(5(4(0(x))))) → 3(4(4(0(5(2(x))))))

Used ordering: Polynomial interpretation [POLO]:

POL(0(x1)) = 3 + x1   
POL(1(x1)) = 2·x1   
POL(11(x1)) = 3·x1   
POL(2(x1)) = 1 + x1   
POL(3(x1)) = 3 + 2·x1   
POL(4(x1)) = 1 + 2·x1   
POL(5(x1)) = 2 + 2·x1   

(22) Obligation:

Q DP problem:
P is empty.
R is empty.
Q is empty.
We have to consider all minimal (P,Q,R)-chains.

(23) PisEmptyProof (EQUIVALENT transformation)

The TRS P is empty. Hence, there is no (P,Q,R) chain.
