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