Perhaps you should try some spelling variations:
"image processing algorithm" » "image routing algorithm" (Expand Search), "image tracking algorithm" (Expand Search), "image boosting algorithm" (Expand Search)
"fold modeling algorithm" » "fold making algorithm" (Expand Search), "field modeling algorithm" (Expand Search), "flood modeling algorithm" (Expand Search), "yield modeling 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: (("present data algorithm") OR ((("image processing algorithm") OR ("fold modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present data algorithm\") OR (((\"image processing algorithm\") OR (\"fold modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( present data algorithm ) OR ((( image processing algorithm ) OR ( fold modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present data algorithm") OR ((("image processing algorithm") OR ("fold modeling algorithm"))))*.
