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