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)
"settlement data algorithm" » "settlement data algorithms" (Expand Search), "settlement update algorithm" (Expand Search), "settlement 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: (("settlement data algorithm") OR ((("data tracking algorithm") OR ("based modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"settlement data algorithm\") OR (((\"data tracking algorithm\") OR (\"based modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( settlement data algorithm ) OR ((( data tracking algorithm ) OR ( based modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("settlement data algorithm") OR ((("data tracking algorithm") OR ("based modeling algorithm"))))*.
