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)
"experiments based algorithm" » "experiments showed algorithm" (Expand Search), "experimental basis algorithm" (Expand Search), "experimental case algorithm" (Expand Search)
"element g algorithms" » "element _ algorithms" (Expand Search), "element 5 algorithms" (Expand Search), "element ml algorithms" (Expand Search), "elements _ 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 g algorithms") OR ("experiments based algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element g algorithms\") OR (\"experiments based algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element g algorithms ) OR ( experiments based algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element g algorithms") OR ("experiments based algorithm"))))*.
