Perhaps you should try some spelling variations:
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client matching algorithm" (Expand Search)
"client mining algorithm" » "client finding algorithm" (Expand Search), "client making algorithm" (Expand Search), "client training algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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: (((("client sampling algorithm") OR ("client mining algorithm"))) OR ("element method algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client sampling algorithm\") OR (\"client mining algorithm\"))) OR (\"element method algorithm\"))".
• Removing quotes may allow a broader search: (((( client sampling algorithm ) OR ( client mining algorithm ))) OR ( element method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("client sampling algorithm") OR ("client mining algorithm"))) OR ("element method algorithm"))*.
