Perhaps you should try some spelling variations:
"element matching algorithm" » "element mining algorithm" (Expand Search), "element sampling algorithm" (Expand Search), "element tracking algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "employment matching algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"present model algorithm" » "present novel algorithm" (Expand Search), "element model algorithm" (Expand Search), "rodent model algorithm" (Expand Search)
"present forest algorithm" » "present free algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("present forest algorithm") OR ("present model algorithm"))) OR ("element matching algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present forest algorithm\") OR (\"present model algorithm\"))) OR (\"element matching algorithm\"))".
• Removing quotes may allow a broader search: (((( present forest algorithm ) OR ( present model algorithm ))) OR ( element matching algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present forest algorithm") OR ("present model algorithm"))) OR ("element matching algorithm"))*.
