Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element new algorithm" » "element novel algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element te algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "elements ree algorithm" (Expand Search)
"element ree algorithm" » "element tree algorithms" (Expand Search), "element em algorithm" (Expand Search), "element rf algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "element te 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 new algorithm") OR ("element ree algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"client sampling algorithm\") OR (((\"element new algorithm\") OR (\"element ree algorithm\"))))".
• Removing quotes may allow a broader search: (( client sampling algorithm ) OR ((( element new algorithm ) OR ( element ree algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("client sampling algorithm") OR ((("element new algorithm") OR ("element ree algorithm"))))*.
