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:

f(X) → if(X, c, n__f(true))
if(true, X, Y) → X
if(false, X, Y) → activate(Y)
f(X) → n__f(X)
activate(n__f(X)) → f(X)
activate(X) → X

Q is empty.

if(true, X, Y) → X
if(false, X, Y) → activate(Y)

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

f(X) → if(X, c, n__f(true))
if(true, X, Y) → X
if(false, X, Y) → activate(Y)
f(X) → n__f(X)
activate(n__f(X)) → f(X)
activate(X) → X

Q is empty.
The following rules can be removed by the rule removal processor [15] because they are oriented strictly by a polynomial ordering:

if(false, X, Y) → activate(Y)
activate(n__f(X)) → f(X)
activate(X) → X
Used ordering:
Polynomial interpretation [25]:

POL(activate(x1)) = 1 + x1   
POL(c) = 0   
POL(f(x1)) = 2·x1   
POL(false) = 2   
POL(if(x1, x2, x3)) = 2·x1 + 2·x2 + 2·x3   
POL(n__f(x1)) = 2·x1   
POL(true) = 0
