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)) -> 2nd(cons1(X, X1))
   2nd(cons1(X, cons(Y))) -> Y
   from(X) -> cons(X)



Outermost Strategy.

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

(1) OutermostNonTerminationProof (COMPLETE)
Term rewrite system R:
The TRS R consists of the following rules:

   2nd(cons(X)) -> 2nd(cons1(X, X1))
   2nd(cons1(X, cons(Y))) -> Y
   from(X) -> cons(X)



Outermost Strategy.

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

2nd(cons(X)) -> 2nd(cons1(X, 2nd(cons(X)))) with rule 2nd(cons(X'')) -> 2nd(cons1(X'', X1)) at position [] and matcher [X'' / X, X1 / 2nd(cons(X))]

Now an instance of the first term with Matcher [ ] occurs in the last term at position [0,1].

Context: 2nd(cons1(X, []))

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