Perhaps you should try some spelling variations:
"text processing algorithm" » "text modeling algorithm" (Expand Search), "text routing algorithm" (Expand Search), "text tracking algorithm" (Expand Search), "time processing algorithm" (Expand Search), "post processing algorithm" (Expand Search), "waste processing algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (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: (("element cnn algorithm") OR ((("text processing algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element cnn algorithm\") OR (((\"text processing algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( element cnn algorithm ) OR ((( text processing algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element cnn algorithm") OR ((("text processing algorithm") OR ("element method algorithm"))))*.
