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