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