Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"elements other algorithms" » "elements three algorithms" (Expand Search), "elements based algorithms" (Expand Search), "elements four 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 each algorithm" (Expand Search), "patient 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 ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements other algorithms\") OR (\"present data algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements other algorithms ) OR ( present data algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements other algorithms") OR ("present data algorithm"))) OR ("client sampling algorithm"))*.
