Perhaps you should try some spelling variations:
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client mining algorithm" (Expand Search)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (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 method algorithm") OR ("client sampling algorithm"))) OR ("present data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements method algorithm\") OR (\"client sampling algorithm\"))) OR (\"present data algorithm\"))".
• Removing quotes may allow a broader search: (((( elements method algorithm ) OR ( client sampling algorithm ))) OR ( present data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements method algorithm") OR ("client sampling algorithm"))) OR ("present data algorithm"))*.
