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)
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"element each algorithm" » "element search algorithm" (Expand Search), "element means algorithm" (Expand Search), "element data algorithm" (Expand Search), "element mesh 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: (((("element based algorithms") OR ("element each algorithm"))) OR ("data processing algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element based algorithms\") OR (\"element each algorithm\"))) OR (\"data processing algorithm\"))".
• Removing quotes may allow a broader search: (((( element based algorithms ) OR ( element each algorithm ))) OR ( data processing algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element based algorithms") OR ("element each algorithm"))) OR ("data processing algorithm"))*.
