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)
"data backing algorithm" » "data tracking algorithm" (Expand Search), "data making algorithm" (Expand Search), "data tracking algorithms" (Expand Search)
"element network algorithm" » "element new algorithm" (Expand Search), "alignment network 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 ("data backing algorithm"))) OR ("element network algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data processing algorithm\") OR (\"data backing algorithm\"))) OR (\"element network algorithm\"))".
• Removing quotes may allow a broader search: (((( data processing algorithm ) OR ( data backing algorithm ))) OR ( element network algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data processing algorithm") OR ("data backing algorithm"))) OR ("element network algorithm"))*.
