Perhaps you should try some spelling variations:
"element mapping algorithm" » "element sampling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element mining algorithm" » "element learning algorithm" (Expand Search), "element means algorithm" (Expand Search), "element bonding algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"elemental rf algorithm" » "elemental xrd algorithm" (Expand Search), "elemental iron algorithm" (Expand Search), "elemental _ algorithm" (Expand Search), "elemental em algorithm" (Expand Search), "elemental ii 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 rf algorithm") OR ((("element mapping algorithm") OR ("element mining algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elemental rf algorithm\") OR (((\"element mapping algorithm\") OR (\"element mining algorithm\"))))".
• Removing quotes may allow a broader search: (( elemental rf algorithm ) OR ((( element mapping algorithm ) OR ( element mining algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elemental rf algorithm") OR ((("element mapping algorithm") OR ("element mining algorithm"))))*.
