Perhaps you should try some spelling variations:
"element sampling algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "client sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"elements over algorithm" » "elements novel algorithm" (Expand Search), "elements other algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements under algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "events over algorithm" (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: (("relevant data algorithms") OR ((("element sampling algorithm") OR ("elements over algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithms\") OR (((\"element sampling algorithm\") OR (\"elements over algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithms ) OR ((( element sampling algorithm ) OR ( elements over algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithms") OR ((("element sampling algorithm") OR ("elements over algorithm"))))*.
