Perhaps you should try some spelling variations:
communication cost » communication cross, communication case, communication control
euclidean dspace » euclidean space, euclidean spaces, euclidean distance
euclidean plane » euclidean space, euclidean spaces
euclidean half » euclidean ball, euclidean phase, euclidean case
cost a » cost _

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication cost a motion ((((euclidean half) or (euclidean plane))) or (euclidean dspace))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication cost a motion ((((euclidean half) OR (euclidean plane))) OR (euclidean dspace)).
• Adding a wildcard symbol may retrieve word variants: communication cost a motion ((((euclidean half) or (euclidean plane))) or (euclidean dspace))*.
