Q restricted rewrite system:
The TRS R consists of the following rules:

a(a(b(x1))) → b(b(c(a(c(x1)))))
a(c(x1)) → a(a(x1))

Q is empty.

(1) QTRS Reverse (EQUIVALENT transformation)

We applied the QTRS Reverse Processor [REVERSE].

(2) Obligation:

Q restricted rewrite system:
The TRS R consists of the following rules:

b(a(a(x))) → c(a(c(b(b(x)))))
c(a(x)) → a(a(x))

Q is empty.

(3) NonTerminationProof (EQUIVALENT transformation)

We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.
