Perhaps you should try some spelling variations:
communication cost » communication cross, communication case, communication control
euclidean dspaces » euclidean spaces, euclidean distances, euclidean subspaces
euclidean half » euclidean ball, euclidean phase, euclidean case
a motions » a motion, _ motions, i motions
cost a » cost _
dspaces » ddspaces
space » dspace

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 motions ((((euclidean half) or (euclidean dspaces))) or (euclidean space))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication cost a motions ((((euclidean half) OR (euclidean dspaces))) OR (euclidean space)).
• Adding a wildcard symbol may retrieve word variants: communication cost a motions ((((euclidean half) or (euclidean dspaces))) or (euclidean space))*.
