YES Termination w.r.t. Q proof of /home/cern_httpd/provide/research/cycsrs/tpdb/TPDB-d9b80194f163/SRS_Standard/Zantema_04/z028.srs

(0) Obligation:

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

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

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:

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

Q is empty.

(3) Strip Symbols Proof (SOUND transformation)

We were given the following TRS:

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

By stripping symbols from the only rule of the system, we obtained the following TRS [ENDRULLIS]:

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

(4) Obligation:

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

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

Q is empty.

(5) RFCMatchBoundsTRSProof (EQUIVALENT transformation)

Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 1. This implies Q-termination of R.
The following rules were used to construct the certificate:

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

7, 8, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37

Node 7 is start node and node 8 is final node.

Those nodes are connected through the following edges:

  • 7 to 24 labelled b_1(0)
  • 8 to 8 labelled #_1(0)
  • 24 to 25 labelled a_1(0)
  • 25 to 26 labelled b_1(0)
  • 26 to 27 labelled a_1(0)
  • 27 to 28 labelled b_1(0)
  • 28 to 29 labelled a_1(0)
  • 28 to 31 labelled b_1(1)
  • 29 to 30 labelled a_1(0)
  • 29 to 31 labelled b_1(1)
  • 30 to 8 labelled a_1(0)
  • 30 to 31 labelled b_1(1)
  • 31 to 32 labelled a_1(1)
  • 32 to 33 labelled b_1(1)
  • 33 to 34 labelled a_1(1)
  • 34 to 35 labelled b_1(1)
  • 35 to 36 labelled a_1(1)
  • 35 to 31 labelled b_1(1)
  • 36 to 37 labelled a_1(1)
  • 36 to 31 labelled b_1(1)
  • 37 to 8 labelled a_1(1)
  • 37 to 31 labelled b_1(1)
