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 new algorithm" » "element novel algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element te algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element ore 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 new algorithm") OR ("element rf algorithm"))) OR ("element mapping algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element new algorithm\") OR (\"element rf algorithm\"))) OR (\"element mapping algorithm\"))".
• Removing quotes may allow a broader search: (((( element new algorithm ) OR ( element rf algorithm ))) OR ( element mapping algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element new algorithm") OR ("element rf algorithm"))) OR ("element mapping algorithm"))*.
