communication creating » communication relating
method extending » methods extending, method extensions, method extension
creating method » coating method, clearing method, heating method
state spaces » state space
tuple spaces » tuple space, type spaces, triple space
shape spaces » shape space, shared spaces, type 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 creating method extending ((((state spaces) or (tuple spaces))) or (shape spaces))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication creating method extending ((((state spaces) OR (tuple spaces))) OR (shape spaces)).
• Adding a wildcard symbol may retrieve word variants: communication creating method extending ((((state spaces) or (tuple spaces))) or (shape spaces))*.
