Talvez debería tentar con algunhas variantes ortográficas:
information propagation » information presentation, information organization
programming recursions » programming decisions, programming decision, programming version
programming recursion » programming decision, programming session, programming decisions
concepts cited » concepts cases, concepts case, concepts care

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: information propagation ((programming recursion) OR (programming recursions)) concepts cited~.
• Adding a wildcard symbol may retrieve word variants: information propagation ((programming recursion) or (programming recursions)) concepts cited*.
