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)
"elements other algorithms" » "elements three algorithms" (Expand Search), "elements tree algorithms" (Expand Search), "elements both algorithms" (Expand Search), "elements over algorithms" (Expand Search), "elements under algorithms" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data algorithm" (Expand Search)

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

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