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 finding algorithm" » "element mining algorithm" (Expand Search), "element filtering algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "recent finding algorithm" (Expand Search), "present findings algorithm" (Expand Search)
"elemental _ algorithm" » "elements _ 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 _ algorithm") OR ((("element mapping algorithm") OR ("element finding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elemental _ algorithm\") OR (((\"element mapping algorithm\") OR (\"element finding algorithm\"))))".
• Removing quotes may allow a broader search: (( elemental _ algorithm ) OR ((( element mapping algorithm ) OR ( element finding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elemental _ algorithm") OR ((("element mapping algorithm") OR ("element finding algorithm"))))*.
