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