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