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