Outermost Termination of the given OTRS could be disproven:

(0) OTRS
(1) OutermostNonTerminationProof [COMPLETE, 0 ms]
(2) NO


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

(0)
Obligation:
Term rewrite system R:
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



Outermost Strategy.

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

(1) OutermostNonTerminationProof (COMPLETE)
Term rewrite system R:
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



Outermost Strategy.

---------- Loop: ----------

2nd(cons(X)) -> head(2nd(cons(X))) with rule 2nd(cons(X'')) -> head(XS) at position [] and matcher [X'' / X, XS / 2nd(cons(X))]

Now an instance of the first term with Matcher [ ] occurs in the last term at position [0].

Context: head([])

We used [THIEMANN_LOOPS_UNDER_STRATEGIES] to show that this Loop is an Outermost-Loop.
