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