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