Perhaps you should try some spelling variations:
communication selection » communication section, communication selecting, communication delegation
selection methods » selection method, detection methods, collection 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.

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