Perhaps you should try some spelling variations:
"element sampling algorithm" » "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"elements based algorithm" » "experiments based algorithm" (Expand Search), "elements related algorithm" (Expand Search)
"elements fe algorithms" » "elements de algorithms" (Expand Search), "elements five algorithms" (Expand Search), "elements _ algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "elements res algorithms" (Expand Search), "elements uce algorithms" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("elements fe algorithms") OR ("elements based algorithm"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements fe algorithms\") OR (\"elements based algorithm\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements fe algorithms ) OR ( elements based algorithm ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements fe algorithms") OR ("elements based algorithm"))) OR ("element sampling algorithm"))*.
