Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"elements based algorithm" » "experiments based algorithm" (Expand Search), "elements related algorithm" (Expand Search)
"elements de algorithms" » "elements _ algorithms" (Expand Search), "elements ml algorithms" (Expand Search), "elements rl algorithms" (Expand Search), "elements fe algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "elements res algorithms" (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 de algorithms") OR ("elements based algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements de algorithms\") OR (\"elements based algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements de algorithms ) OR ( elements based algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements de algorithms") OR ("elements based algorithm"))) OR ("client sampling algorithm"))*.
