MAYBE

Problem:
 strict:
  minus(x,0()) -> x
  minus(s(x),s(y)) -> minus(x,y)
  double(0()) -> 0()
  double(s(x)) -> s(s(double(x)))
  plus(0(),y) -> y
  plus(s(x),y) -> s(plus(x,y))
  plus(s(x),y) -> plus(x,s(y))
  plus(s(x),y) -> s(plus(minus(x,y),double(y)))
 weak:
  rand(x) -> x
  rand(x) -> rand(s(x))
