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

(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   a(x1) -> x1
   a(x1) -> b(x1)
   a(b(x1)) -> b(c(x1))
   c(c(x1)) -> a(c(a(x1)))

Q is empty.

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

(1) QTRS Reverse (EQUIVALENT)
We applied the QTRS Reverse Processor [REVERSE].
----------------------------------------

(2)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   a(x1) -> x1
   a(x1) -> b(x1)
   b(a(x1)) -> c(b(x1))
   c(c(x1)) -> a(c(a(x1)))

Q is empty.

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

(3) DependencyPairsProof (EQUIVALENT)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.
----------------------------------------

(4)
Obligation:
Q DP problem:
The TRS P consists of the following rules:

   A(x1) -> B(x1)
   B(a(x1)) -> C(b(x1))
   B(a(x1)) -> B(x1)
   C(c(x1)) -> A(c(a(x1)))
   C(c(x1)) -> C(a(x1))
   C(c(x1)) -> A(x1)

The TRS R consists of the following rules:

   a(x1) -> x1
   a(x1) -> b(x1)
   b(a(x1)) -> c(b(x1))
   c(c(x1)) -> a(c(a(x1)))

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

(5) QDPOrderProof (EQUIVALENT)
We use the reduction pair processor [LPAR04,JAR06].


The following pairs can be oriented strictly and are deleted.

   B(a(x1)) -> C(b(x1))
The remaining pairs can at least be oriented weakly.
Used ordering:  Matrix interpretation [MATRO] with arctic natural numbers [ARCTIC]:
