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