Perhaps you should try some spelling variations:
"image processing algorithm" » "image modeling algorithm" (Expand Search), "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search)
"present update algorithm" » "present pass algorithm" (Expand Search), "present data algorithms" (Expand Search), "present ipca algorithm" (Expand Search), "present data algorithm" (Expand Search)
"recent data algorithm" » "recent data algorithms" (Expand Search), "recent atlas algorithm" (Expand Search), "recent each algorithm" (Expand Search), "relevant 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: (("image processing algorithm") OR ((("recent data algorithm") OR ("present update algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image processing algorithm\") OR (((\"recent data algorithm\") OR (\"present update algorithm\"))))".
• Removing quotes may allow a broader search: (( image processing algorithm ) OR ((( recent data algorithm ) OR ( present update algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image processing algorithm") OR ((("recent data algorithm") OR ("present update algorithm"))))*.
