Perhaps you should try some spelling variations:
"element sampling algorithm" » "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"client mining algorithm" » "client learning algorithm" (Expand Search)
"client means algorithm" » "client search algorithm" (Expand Search), "client needs algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("element sampling algorithm") OR ((("client mining algorithm") OR ("client means algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element sampling algorithm\") OR (((\"client mining algorithm\") OR (\"client means algorithm\"))))".
• Removing quotes may allow a broader search: (( element sampling algorithm ) OR ((( client mining algorithm ) OR ( client means algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element sampling algorithm") OR ((("client mining algorithm") OR ("client means algorithm"))))*.
