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