Termination of the given GTRS could be disproven:

(0) GTRS
(1) CritRuleProof [COMPLETE, 0 ms]
(2) NO


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

(0)
Obligation:
Generalized rewrite system (where rules with free variables on rhs are allowed):
The TRS R consists of the following rules:

   2nd(cons(X)) -> head(XS)
   sel(s(N), cons(X)) -> sel(N, XS)
   from(X) -> cons(X)
   head(cons(X)) -> X
   take(0, XS) -> nil
   take(s(N), cons(X)) -> cons(X)
   sel(0, cons(X)) -> X


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

(1) CritRuleProof (COMPLETE)
The rule 2nd(cons(X)) -> head(XS) contains free variables in its right-hand side. Hence the TRS is not-terminating.
----------------------------------------

(2)
NO
