Execution Time	Unknown
Answer	TIMEOUT
Input	CSR 04 Ex1 Luc04b

stdout:

TIMEOUT

'Fastest (timeout of 60.0 seconds)'
-----------------------------------
Answer:           TIMEOUT
Input Problem:    innermost runtime-complexity with respect to
  Rules:
    {  nats() -> cons(0(), incr(nats()))
     , pairs() -> cons(0(), incr(odds()))
     , odds() -> incr(pairs())
     , incr(cons(X, XS)) -> cons(s(X), incr(XS))
     , head(cons(X, XS)) -> X
     , tail(cons(X, XS)) -> XS}

Proof Output:
  Computation stopped due to timeout after 60.0 seconds
