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