Perhaps you should try some spelling variations:
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"element within algorithm" » "element switching algorithm" (Expand Search), "element twisting algorithm" (Expand Search), "element matching algorithm" (Expand Search), "elements within algorithm" (Expand Search), "present within algorithm" (Expand Search)
"element based algorithm" » "engagement based 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 based algorithm") OR ((("element within algorithm") OR ("element mapping algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element based algorithm\") OR (((\"element within algorithm\") OR (\"element mapping algorithm\"))))".
• Removing quotes may allow a broader search: (( element based algorithm ) OR ((( element within algorithm ) OR ( element mapping algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element based algorithm") OR ((("element within algorithm") OR ("element mapping algorithm"))))*.
