Perhaps you should try some spelling variations:
"based mapping algorithm" » "based making algorithm" (Expand Search), "based mining algorithm" (Expand Search), "based learning algorithm" (Expand Search), "based machine algorithm" (Expand Search)
"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 algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

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