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

(0) QTRS
(1) QTRS Reverse [EQUIVALENT, 0 ms]
(2) QTRS
(3) RFCMatchBoundsTRSProof [EQUIVALENT, 0 ms]
(4) YES


----------------------------------------

(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   f(g(X)) -> g(f(f(X)))
   f(h(X)) -> h(g(X))

Q is empty.

----------------------------------------

(1) QTRS Reverse (EQUIVALENT)
We applied the QTRS Reverse Processor [REVERSE].
----------------------------------------

(2)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   g(f(X)) -> f(f(g(X)))
   h(f(X)) -> g(h(X))

Q is empty.

----------------------------------------

(3) RFCMatchBoundsTRSProof (EQUIVALENT)
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:

   g(f(X)) -> f(f(g(X)))
   h(f(X)) -> g(h(X))

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
33, 34, 77, 78, 79, 80, 81, 82

Node 33 is start node and node 34 is final node.

Those nodes are connected through the following edges:

* 33 to 77 labelled f_1(0)* 33 to 79 labelled g_1(0)* 34 to 34 labelled #_1(0)* 77 to 78 labelled f_1(0)* 78 to 34 labelled g_1(0)* 78 to 80 labelled f_1(1)* 79 to 34 labelled h_1(0)* 79 to 82 labelled g_1(1)* 80 to 81 labelled f_1(1)* 81 to 34 labelled g_1(1)* 81 to 80 labelled f_1(1)* 82 to 34 labelled h_1(1)* 82 to 82 labelled g_1(1)
