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), "elements ree algorithm" (Expand Search), "elements mges algorithm" (Expand Search)
"events over algorithm" » "events novel algorithm" (Expand Search), "events other algorithms" (Expand Search), "events new algorithm" (Expand Search), "events per algorithm" (Expand Search), "events after 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: (((("elements over algorithm") OR ("events over algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements over algorithm\") OR (\"events over algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements over algorithm ) OR ( events over algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements over algorithm") OR ("events over algorithm"))) OR ("client sampling algorithm"))*.
