Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"elements over algorithm" » "elements novel algorithm" (Expand Search), "elements other algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements under algorithm" (Expand Search), "events over algorithm" (Expand Search), "elements ree algorithm" (Expand Search)
"element study algorithm" » "present study algorithm" (Expand Search), "recent study algorithm" (Expand Search), "event study algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("element study algorithm") OR ((("client sampling algorithm") OR ("elements over algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element study algorithm\") OR (((\"client sampling algorithm\") OR (\"elements over algorithm\"))))".
• Removing quotes may allow a broader search: (( element study algorithm ) OR ((( client sampling algorithm ) OR ( elements over algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element study algorithm") OR ((("client sampling algorithm") OR ("elements over algorithm"))))*.
