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