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) → cons(X, n__f(g(X)))
g(0) → s(0)
g(s(X)) → s(s(g(X)))
sel(0, cons(X, Y)) → X
sel(s(X), cons(Y, Z)) → sel(X, activate(Z))
f(X) → n__f(X)
activate(n__f(X)) → f(X)
activate(X) → X

Q is empty.

g(0) → s(0)
g(s(X)) → s(s(g(X)))

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

Lexicographic path order with status [19].
Quasi-Precedence:
sel2 > activate1 > f1 > cons2
sel2 > activate1 > f1 > nf1
sel2 > activate1 > f1 > [g1, 0] > s1

Status:
sel2: [1,2]
f1: [1]
s1: [1]
0: multiset
nf1: [1]
g1: [1]
cons2: [1,2]
activate1: [1]
