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)
"element modbo algorithm" » "element model 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 modbo algorithm") OR ("client sampling algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element modbo algorithm\") OR (\"client sampling algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( element modbo algorithm ) OR ( client sampling algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element modbo algorithm") OR ("client sampling algorithm"))) OR ("element method algorithm"))*.
