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 based algorithm" » "engagement based algorithm" (Expand Search)
"element ii algorithm" » "element _ algorithm" (Expand Search), "element _ algorithms" (Expand Search), "element g algorithm" (Expand Search), "element te algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element ii algorithm") OR ("client sampling algorithm"))) OR ("element based algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element ii algorithm\") OR (\"client sampling algorithm\"))) OR (\"element based algorithm\"))".
• Removing quotes may allow a broader search: (((( element ii algorithm ) OR ( client sampling algorithm ))) OR ( element based algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element ii algorithm") OR ("client sampling algorithm"))) OR ("element based algorithm"))*.
