Problem SK90 2.39

Tool Bounds

Execution Time	60.03188ms
Answer	TIMEOUT
Input	SK90 2.39

stdout:

TIMEOUT

We consider the following Problem:

  Strict Trs:
    {  ++(.(x, y), z) -> .(x, ++(y, z))
     , ++(nil(), y) -> y
     , null(.(x, y)) -> false()
     , null(nil()) -> true()
     , cdr(.(x, y)) -> y
     , car(.(x, y)) -> x
     , rev(.(x, y)) -> ++(rev(y), .(x, nil()))
     , rev(nil()) -> nil()}
  StartTerms: all
  Strategy: none

Certificate: TIMEOUT

Proof:
  Computation stopped due to timeout after 60.0 seconds.

Arrrr..
