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