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