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