Termination w.r.t. Q of the following Term Rewriting System could be proven:

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

a__ca__f(g(c))
a__f(g(X)) → g(X)
mark(c) → a__c
mark(f(X)) → a__f(X)
mark(g(X)) → g(X)
a__cc
a__f(X) → f(X)

Q is empty.

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

a__ca__f(g(c))
a__f(g(X)) → g(X)
mark(c) → a__c
mark(f(X)) → a__f(X)
mark(g(X)) → g(X)
a__cc
a__f(X) → f(X)

Q is empty.

We use [27] with the following order to prove termination.

Knuth-Bendix order [24] with precedence:
trivial

and weight map:

mark_1=5
c=1
a__c=5
f_1=1
a__f_1=2
g_1=1
