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