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

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

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

The TRS R consists of the following rules:

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

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

(5) MRRProof (EQUIVALENT)
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:

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