Hi Stefan, I had the same problem, I'll send you my solution this afternoon. I'll be away for a week after tonight though. I created a recursive algorithm, which would keep track of the depth of the tree. When the maximum depth was almost reached, I would limit the type of constructors it could choose to constructors with the least amount of arguments. I would rank constructors on their complexity. 0 for constructors without arguments, 1 for constructors with primitive (and String) arguments and 2 for constructors with complex arguments. When the maximum depth was reached, I would use a null node.
