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 de algorithms" » "element mdem algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements fe algorithms" (Expand Search), "element fbe algorithms" (Expand Search)
"element gnb algorithm" » "element mnb algorithm" (Expand Search), "element anbs algorithm" (Expand Search), "element cnn algorithm" (Expand Search), "element g 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 de algorithms") OR ("element gnb algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"data processing algorithm\") OR (((\"element de algorithms\") OR (\"element gnb algorithm\"))))".
• Removing quotes may allow a broader search: (( data processing algorithm ) OR ((( element de algorithms ) OR ( element gnb algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("data processing algorithm") OR ((("element de algorithms") OR ("element gnb algorithm"))))*.
