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)
"element study algorithm" » "element wsindy algorithm" (Expand Search), "element td3 algorithm" (Expand Search), "element seu algorithm" (Expand Search), "relevant study algorithm" (Expand Search), "present study algorithm" (Expand Search), "recent study algorithm" (Expand Search)
"element based algorithm" » "engagement based 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 based algorithm") OR ("element study algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithm\") OR (\"element study algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithm ) OR ( element study algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithm") OR ("element study algorithm"))) OR ("client sampling algorithm"))*.
