Problem Der95 17

Tool Bounds

Execution Time	60.03409ms
Answer	TIMEOUT
Input	Der95 17

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  i(.(x, y)) -> .(i(y), i(x))
     , .(.(x, y), z) -> .(x, .(y, z))
     , .(y, .(i(y), z)) -> z
     , .(i(y), .(y, z)) -> z
     , i(i(x)) -> x
     , i(1()) -> 1()
     , .(x, i(x)) -> 1()
     , .(i(x), x) -> 1()
     , .(x, 1()) -> x
     , .(1(), x) -> x}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.
