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