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