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:

   sel(0, cons) -> X
   sel(s, cons) -> sel(X, Z)
   dbl(0) -> 0
   dbl(s) -> s
   dbls(nil) -> nil
   dbls(cons) -> cons
   indx(nil) -> nil
   indx(cons) -> cons
   from -> cons


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

(1) CritRuleProof (COMPLETE)
The rule sel(0, cons) -> X contains free variables in its right-hand side. Hence the TRS is not-terminating.
----------------------------------------

(2)
NO
