- The paper then distinguishes between structural recursion, where the related data definition happens to be self-referential, requiring usually a straightforward design process, and generative recursion, where new problem data is generated in the middle of the problem-solving process and the problem solving method is re-used, often requiring " ad hoc " mathematical insight, and stresses how this distinction makes their approach scalable to the object-oriented ( OO ) world.
