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 novel algorithm" » "element forest algorithm" (Expand Search), "element model algorithm" (Expand Search), "element ore algorithm" (Expand Search), "elements over 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: (((("data processing algorithm") OR ("image modeling algorithm"))) OR ("element novel algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"image modeling algorithm\"))) OR (\"element novel algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( image modeling algorithm ))) OR ( element novel algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("image modeling algorithm"))) OR ("element novel algorithm"))*.
