Perhaps you should try some spelling variations:
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element mining algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling 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)

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