Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"sleep processing algorithm" » "speech processing algorithm" (Expand Search), "level processing algorithm" (Expand Search), "salmon processing 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: (("elements new algorithm") OR ((("client sampling algorithm") OR ("sleep processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements new algorithm\") OR (((\"client sampling algorithm\") OR (\"sleep processing algorithm\"))))".
• Removing quotes may allow a broader search: (( elements new algorithm ) OR ((( client sampling algorithm ) OR ( sleep processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements new algorithm") OR ((("client sampling algorithm") OR ("sleep processing algorithm"))))*.
