Perhaps you should try some spelling variations:
"implement cosine algorithm" » "implement colony algorithm" (Expand Search), "implemented cosine algorithm" (Expand Search), "implementing cosine algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"element cnn algorithm" » "element rd algorithm" (Expand Search), "element colony 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: (("implement cosine algorithm") OR ((("element cnn algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement cosine algorithm\") OR (((\"element cnn algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( implement cosine algorithm ) OR ((( element cnn algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement cosine algorithm") OR ((("element cnn algorithm") OR ("element method algorithm"))))*.
