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

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

Q is empty.

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:

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

3, 4, 13, 14, 15, 16, 17, 18, 19, 20, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76

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

Those nodes are connected through the following edges:

  • 3 to 13 labelled a_1(0)
  • 4 to 4 labelled #_1(0)
  • 13 to 14 labelled a_1(0)
