Termination w.r.t. Q proof of TRS/TRCSREx1_Zan97

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__g(X) → a__h(X)
a__c → d
a__h(d) → a__g(c)
mark(g(X)) → a__g(X)
mark(h(X)) → a__h(X)
mark(c) → a__c
mark(d) → d
a__g(X) → g(X)
a__h(X) → h(X)
a__c → c

Q is empty.

We use [23] with the following order to prove termination.

Recursive Path Order [2].
Precedence:

mark₁ > a_{_c} > d > a_{_g₁} > a_{_h₁} > h₁
mark₁ > a_{_c} > d > a_{_g₁} > g₁
mark₁ > a_{_c} > d > c
