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)
"present data algorithms" » "present art algorithms" (Expand Search), "present all algorithms" (Expand Search), "present both algorithms" (Expand Search), "present update algorithms" (Expand Search), "present atlas algorithms" (Expand Search), "present each algorithms" (Expand Search), "presence data algorithms" (Expand Search), "present day algorithms" (Expand Search), "recent data algorithms" (Expand Search)
"relevant data algorithm" » "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search), "relevant each 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: (((("relevant data algorithm") OR ("element sampling algorithm"))) OR ("present data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"element sampling algorithm\"))) OR (\"present data algorithms\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( element sampling algorithm ))) OR ( present data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("element sampling algorithm"))) OR ("present data algorithms"))*.
