Execution Time	60.033356ms
Answer	TIMEOUT
Input	SK90 2.14

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  half(double(x)) -> x
     , if(s(x), y, z) -> z
     , if(0(), y, z) -> y
     , -(s(x), s(y)) -> -(x, y)
     , -(x, 0()) -> x
     , half(s(s(x))) -> s(half(x))
     , half(s(0())) -> 0()
     , half(0()) -> 0()
     , double(s(x)) -> s(s(double(x)))
     , double(0()) -> 0()}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.
