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