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