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)
"develop based algorithms" » "develop based algorithm" (Expand Search), "developed based algorithms" (Expand Search), "develop masld algorithms" (Expand Search), "development based algorithms" (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)

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