Perhaps you should try some spelling variations:
"image 3_using algorithm" » "image routing algorithm" (Expand Search), "image using algorithms" (Expand Search), "image twisting algorithm" (Expand Search), "image 1_using algorithm" (Expand Search), "image 2_using algorithm" (Expand Search), "image 4_using 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: (("image 3_using algorithm") OR ((("element method algorithm") OR ("element cnn algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"image 3_using algorithm\") OR (((\"element method algorithm\") OR (\"element cnn algorithm\"))))".
• Removing quotes may allow a broader search: (( image 3_using algorithm ) OR ((( element method algorithm ) OR ( element cnn algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("image 3_using algorithm") OR ((("element method algorithm") OR ("element cnn algorithm"))))*.
