(0) Obligation:

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

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

Q is empty.

(3) RFCMatchBoundsTRSProof (EQUIVALENT transformation)

Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 2. This implies Q-termination of R.
The following rules were used to construct the certificate:

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 23, 24, 25, 26, 27, 28, 29, 30, 31, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58

Node 1 is start node and node 2 is final node.

Those nodes are connected through the following edges:

  • 1 to 3 labelled c_1(0)
  • 2 to 2 labelled #_1(0)
  • 3 to 4 labelled a_1(0)
  • 4 to 5 labelled b_1(0)

  • 11 to 2 labelled a_1(0)
  • 11 to 23 labelled c_1(1)

  • 24 to 25 labelled b_1(1)
  • 25 to 26 labelled a_1(1)
