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:

   if(true) -> X
   if(false) -> Y
   fact(X) -> if(zero(X))
   add(0, X) -> X
   add(s(X), Y) -> s(add(X, Y))
   prod(0, X) -> 0
   prod(s(X), Y) -> add(Y, prod(X, Y))
   zero(0) -> true
   zero(s(X)) -> false
   p(s(X)) -> X



Outermost Strategy.

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

   if(true) -> X
   if(false) -> Y
   fact(X) -> if(zero(X))
   add(0, X) -> X
   add(s(X), Y) -> s(add(X, Y))
   prod(0, X) -> 0
   prod(s(X), Y) -> add(Y, prod(X, Y))
   zero(0) -> true
   zero(s(X)) -> false
   p(s(X)) -> X



Outermost Strategy.

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

if(true) -> if(true) with rule if(true) -> X at position [] and matcher [X / if(true)]

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

Context: []

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