Perhaps you should try some spelling variations:
"data tracking algorithm" » "data tracking algorithms" (Expand Search), "data training algorithms" (Expand Search), "data making algorithm" (Expand Search), "path tracking algorithm" (Expand Search), "data backing algorithm" (Expand Search), "uav tracking algorithm" (Expand Search)
"based modeling algorithm" » "based making algorithm" (Expand Search), "based model algorithm" (Expand Search), "based models algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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: (("relevant data algorithm") OR ((("data tracking algorithm") OR ("based modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithm\") OR (((\"data tracking algorithm\") OR (\"based modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithm ) OR ((( data tracking algorithm ) OR ( based modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithm") OR ((("data tracking algorithm") OR ("based modeling algorithm"))))*.
