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 each algorithm" » "elements search algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements crcy algorithm" (Expand Search), "elements uce algorithm" (Expand Search), "experiments each 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 each algorithm") OR ((("client sampling algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements each algorithm\") OR (((\"client sampling algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( elements each algorithm ) OR ((( client sampling algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements each algorithm") OR ((("client sampling algorithm") OR ("element method algorithm"))))*.
