Perhaps you should try some spelling variations:
functions computation » function computation, functions composition, function composition
programming recursion » programming decision, programming session, programming decisions
using conditional » using conventional, using traditional
recursion versus » deduction versus, inclusion versus, recursion arrays
versus visual » various visual, versus actual, senses visual

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((functions computation) OR (using conditional)) programming recursion versus visual~.
• Adding a wildcard symbol may retrieve word variants: ((functions computation) or (using conditional)) programming recursion versus visual*.
