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 based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean 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 mapping algorithm") OR ((("element based algorithms") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element mapping algorithm\") OR (((\"element based algorithms\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( element mapping algorithm ) OR ((( element based algorithms ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element mapping algorithm") OR ((("element based algorithms") OR ("element method algorithm"))))*.
