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)
"elements each algorithm" » "elements search algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements crcy algorithm" (Expand Search), "elements uce algorithm" (Expand Search), "experiments each algorithm" (Expand Search)
"elements upon algorithm" » "elements ppo algorithm" (Expand Search), "elements fusion algorithm" (Expand Search), "elements pso algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements uce algorithm" (Expand Search), "complements upon 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 each algorithm") OR ("elements upon algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements each algorithm\") OR (\"elements upon algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements each algorithm ) OR ( elements upon algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements each algorithm") OR ("elements upon algorithm"))) OR ("client sampling algorithm"))*.
