YES Termination w.r.t. Q proof of /home/cern_httpd/provide/research/cycsrs/examples/collection/a-b.srs

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

0 QTRS
↳1 QTRS Reverse (⇔, 0 ms)
↳2 QTRS
↳3 RFCMatchBoundsTRSProof (⇔, 0 ms)
↳4 YES

(0) Obligation:

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

a(x) → 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(x) → b(x)

Q is empty.

(3) RFCMatchBoundsTRSProof (EQUIVALENT transformation)

Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 0. This implies Q-termination of R.
The following rules were used to construct the certificate:

a(x) → b(x)

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

3, 4

Node 3 is start node and node 4 is final node.

Those nodes are connected through the following edges:

  • 3 to 4 labelled b_1(0)
  • 4 to 4 labelled #_1(0)

(4) YES
