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)
"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)
"elements four algorithms" » "elements group algorithms" (Expand Search), "elements fe algorithms" (Expand Search), "elements over 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: (((("elements four algorithms") OR ("present data algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements four algorithms\") OR (\"present data algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements four algorithms ) OR ( present data algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements four algorithms") OR ("present data algorithm"))) OR ("client sampling algorithm"))*.
