Problem CSR 04 Ex1 Luc04b

Tool Bounds

Execution Time	60.034805ms
Answer	TIMEOUT
Input	CSR 04 Ex1 Luc04b

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  tail(cons(X, XS)) -> XS
     , head(cons(X, XS)) -> X
     , incr(cons(X, XS)) -> cons(s(X), incr(XS))
     , odds() -> incr(pairs())
     , pairs() -> cons(0(), incr(odds()))
     , nats() -> cons(0(), incr(nats()))}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.

Arrrr..
