Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element novel algorithm" » "element forest algorithm" (Expand Search), "element model algorithm" (Expand Search), "present novel algorithm" (Expand Search), "elements over algorithm" (Expand Search)
"present model algorithm" » "present forest algorithm" (Expand Search), "element model algorithm" (Expand Search), "rodent model 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 novel algorithm") OR ("present model algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element novel algorithm\") OR (\"present model algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element novel algorithm ) OR ( present model algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element novel algorithm") OR ("present model algorithm"))) OR ("client sampling algorithm"))*.
