MAYBE

Problem:
 strict:
  le(0(),y) -> true()
  le(s(x),0()) -> false()
  le(s(x),s(y)) -> le(x,y)
  minus(x,0()) -> x
  minus(s(x),s(y)) -> minus(x,y)
  gcd(0(),y) -> y
  gcd(s(x),0()) -> s(x)
  gcd(s(x),s(y)) -> if_gcd(le(y,x),s(x),s(y))
  if_gcd(true(),s(x),s(y)) -> gcd(minus(x,y),s(y))
  if_gcd(false(),s(x),s(y)) -> gcd(minus(y,x),s(x))
 weak:
  rand(x) -> x
  rand(x) -> rand(s(x))
