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 art algorithms" » "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element based algorithms" (Expand Search), "element ore algorithms" (Expand Search), "element data algorithms" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii 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 ((("element cnn algorithm") OR ("element art algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element cnn algorithm\") OR (\"element art algorithms\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element cnn algorithm ) OR ( element art algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element cnn algorithm") OR ("element art algorithms"))))*.
