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