Talvez debería tentar con algunhas variantes ortográficas:
communication cost » communication cross, communication case, communication control
biased precision » based precision, based imprecision, fixed precision
data evolving » data involving, data resolving, data solving
data mapping » data mining, a mapping
cost biased » cost based, color biased
data saving » data sharing, data scaling, data sieving

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 cost biased precision ((((data saving) OR (data evolving))) OR (data mapping))~.
• Adding a wildcard symbol may retrieve word variants: communication cost biased precision ((((data saving) or (data evolving))) or (data mapping))*.
