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