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