Termination w.r.t. Q of the given QTRS could be disproven:

(0) Obligation:

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

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

Q is empty.

(1) NonTerminationProof (EQUIVALENT transformation)

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

Found the self-embedding DerivationStructure:

c a a b a a a → a a b a c a a b a a a b a c c a a b c c a a b

c a a b a a a → a a b a c a a b a a a b a c c a a b c c a a b
by OverlapClosure OC 2

c a a b a → a a b a c c a a b
by original rule (OC 1)

c a a b a a → a a b a a a b a c c a a b c c a a b
by OverlapClosure OC 3

c a a b a a → a a b a c a a b a c c a a b
by OverlapClosure OC 2

c a a b a → a a b a c c a a b
by original rule (OC 1)

c a a b a → a a b a c c a a b
by original rule (OC 1)

c a a b a → a a b a c c a a b
by original rule (OC 1)

(2) NO
