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)
"elements best algorithm" » "elements based algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements pso algorithm" (Expand Search), "elements res algorithm" (Expand Search), "elements b algorithm" (Expand Search)
"element forest algorithm" » "element ore 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 best algorithm") OR ((("client sampling algorithm") OR ("element forest algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements best algorithm\") OR (((\"client sampling algorithm\") OR (\"element forest algorithm\"))))".
• Removing quotes may allow a broader search: (( elements best algorithm ) OR ((( client sampling algorithm ) OR ( element forest algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements best algorithm") OR ((("client sampling algorithm") OR ("element forest algorithm"))))*.
