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 abs algorithm" » "element anbs algorithm" (Expand Search), "element pass algorithm" (Expand Search), "element b algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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 ((("element method algorithm") OR ("element abs algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"client sampling algorithm\") OR (((\"element method algorithm\") OR (\"element abs algorithm\"))))".
• Removing quotes may allow a broader search: (( client sampling algorithm ) OR ((( element method algorithm ) OR ( element abs algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("client sampling algorithm") OR ((("element method algorithm") OR ("element abs algorithm"))))*.
