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