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

(0) QTRS
(1) NonTerminationProof [COMPLETE, 0 ms]
(2) NO


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

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

   a(b(a(b(x)))) -> b(a(b(a(a(b(x))))))

Q is empty.

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

(1) NonTerminationProof (COMPLETE)
We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.

Found the self-embedding DerivationStructure: 
"a b a b a b -> b a b a b a b a a b"
a b a b a b -> b a b a b a b a a b
by OverlapClosure OC 2"a b a b -> b a b a a b
by original rule (OC 1)""a b a b -> b a b a a b
by original rule (OC 1)"

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

(2)
NO
