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