intrusive methods » intensive methods, unobtrusive methods, invasive methods
methods diffusion » networks diffusion, methods decision
whose spaces » phase spaces, shape spaces, whose race
tuple spaces » tuple space, type spaces, triple space

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