NO Termination w.r.t. Q proof of /home/cern_httpd/provide/research/cycsrs/tpdb/TPDB-d9b80194f163/SRS_Standard/Zantema_04/z042.srs

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

0 QTRS
↳1 NonTerminationProof (⇒, 0 ms)
↳2 NO

(0) Obligation:

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

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

Q is empty.

(1) NonTerminationProof (COMPLETE transformation)

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

Found the self-embedding DerivationStructure:
c b a b a b a b a b a b a → a b a b a b c b a b a b a b a b a b a b c b c b a b c b c

c b a b a b a b a b a b a → a b a b a b c b a b a b a b a b a b a b c b c b a b c b c
by OverlapClosure OC 2
c b a b a → a b a b a b c b c
by original rule (OC 1)
c b a b a b a b a → a b a b a b a b a b a b c b c b a b c b c
by OverlapClosure OC 3
c b a b a b a b a → a b a b a b c b a b a b a b c b c
by OverlapClosure OC 2
c b a b a → a b a b a b c b c
by original rule (OC 1)
c b a b a → a b a b a b c b c
by original rule (OC 1)
c b a b a → a b a b a b c b c
by original rule (OC 1)
