Perhaps you should try some spelling variations:
"implement cosine algorithm" » "implement routine algorithm" (Expand Search), "implement colony algorithm" (Expand Search), "implement routing algorithm" (Expand Search), "implement fusion algorithm" (Expand Search)
"neural codingnb algorithm" » "neural coding algorithm" (Expand Search)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ 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 g algorithm"))) OR ("neural codingnb algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement cosine algorithm\") OR (\"element g algorithm\"))) OR (\"neural codingnb algorithm\"))".
• Removing quotes may allow a broader search: (((( implement cosine algorithm ) OR ( element g algorithm ))) OR ( neural codingnb algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implement cosine algorithm") OR ("element g algorithm"))) OR ("neural codingnb algorithm"))*.
