Talvez debería tentar con algunhas variantes ortográficas:
estimation detecting » estimation testing, optimization detecting, estimation determining
detecting method » detection method, selecting method, detection methods
method problems » methods problems, method process
array string » array strong, arrays strings, array sharing
array using » arrays using

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "estimation detecting method problems ((((array string) OR (array format))) OR (array using))~".
• Adding a wildcard symbol may retrieve word variants: estimation detecting method problems ((((array string) OR (array format))) OR (array using))*.
