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