Tool IRC1

Execution Time	Unknown
Answer	MAYBE
Input	CSR 04 ExIntrod GM01

stdout:

MAYBE

Tool IRC2

Execution Time	Unknown
Answer	TIMEOUT
Input	CSR 04 ExIntrod GM01

stdout:

TIMEOUT

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

Proof Output:
  Computation stopped due to timeout after 60.0 seconds
