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

a(b(x)) → b(b(a(x)))

Q is empty.

(1) 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(b(x)) → b(b(a(x)))

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

9113194, 9113195, 9113196, 9113197, 9113199, 9113198

Node 9113194 is start node and node 9113195 is final node.

Those nodes are connect through the following edges:

  • 9113194 to 9113196 labelled b_1(0)
  • 9113195 to 9113195 labelled #_1(0)
  • 9113196 to 9113197 labelled b_1(0)
  • 9113197 to 9113195 labelled a_1(0)
  • 9113197 to 9113198 labelled b_1(1)
  • 9113199 to 9113195 labelled a_1(1)
  • 9113199 to 9113198 labelled b_1(1)
  • 9113198 to 9113199 labelled b_1(1)
