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)
"recent data algorithm" » "recent data algorithms" (Expand Search), "recent update algorithm" (Expand Search), "recent atlas algorithm" (Expand Search), "relevant data algorithm" (Expand Search)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "patient 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: (((("recent data algorithm") OR ("present data algorithm"))) OR ("image tracking algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"recent data algorithm\") OR (\"present data algorithm\"))) OR (\"image tracking algorithm\"))".
• Removing quotes may allow a broader search: (((( recent data algorithm ) OR ( present data algorithm ))) OR ( image tracking algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("recent data algorithm") OR ("present data algorithm"))) OR ("image tracking algorithm"))*.
