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