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 based algorithms" » "elements based algorithm" (Expand Search), "experiments based algorithms" (Expand Search), "elements related algorithms" (Expand Search)
"elemental _ algorithm" » "element _ 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: (((("elemental _ algorithm") OR ("elements based algorithms"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elemental _ algorithm\") OR (\"elements based algorithms\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elemental _ algorithm ) OR ( elements based algorithms ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elemental _ algorithm") OR ("elements based algorithms"))) OR ("client sampling algorithm"))*.
