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)
"image using algorithms" » "image pacing algorithms" (Expand Search), "image nine algorithms" (Expand Search), "image sorting algorithms" (Expand Search), "images using algorithms" (Expand Search), "made using algorithms" (Expand Search), "imaging using algorithms" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "elements cnn 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 ((("image using algorithms") OR ("data processing algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element cnn algorithm\") OR (((\"image using algorithms\") OR (\"data processing algorithm\"))))".
• Removing quotes may allow a broader search: (( element cnn algorithm ) OR ((( image using algorithms ) OR ( data processing algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element cnn algorithm") OR ((("image using algorithms") OR ("data processing algorithm"))))*.
