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)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: "((\"element data algorithm\") OR (((\"data using algorithm\") OR (\"based mapping algorithm\"))))~".
• Removing quotes may allow a broader search: (( element data algorithm ) OR ((( data using algorithm ) OR ( based mapping algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("element data algorithm") OR ((("data using algorithm") OR ("based mapping algorithm"))))*.
