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)
"elements upon algorithms" » "elements using algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements nn algorithms" (Expand Search), "elements ppm algorithms" (Expand Search), "elements uce algorithms" (Expand Search), "complements upon algorithms" (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 ((("element based algorithms") OR ("elements upon algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element based algorithms\") OR (\"elements upon algorithms\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element based algorithms ) OR ( elements upon algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element based algorithms") OR ("elements upon algorithms"))))*.
