Perhaps you should try some spelling variations:
communication iterative » communications iterative, communication interactive, communication literature
iterative methods » operative methods
methods diffusion » networks diffusion, methods decision
whose spaces » phase spaces, shape spaces, whose race
tuple spaces » tuple space, triple space
type spaces » state spaces

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication iterative methods diffusion ((((whose spaces) or (tuple spaces))) or (type spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication iterative methods diffusion ((((whose spaces) OR (tuple spaces))) OR (type spaces)).
• Adding a wildcard symbol may retrieve word variants: communication iterative methods diffusion ((((whose spaces) or (tuple spaces))) or (type spaces))*.
