Perhaps you should try some spelling variations:
"neural cosine algorithm" » "neural colony algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "elements means algorithm" (Expand Search)
"implement cc3d algorithm" » "implement rd algorithm" (Expand Search), "implemented cc3d algorithm" (Expand Search), "implementing cc3d 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 cc3d algorithm") OR ((("element means algorithm") OR ("neural cosine algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement cc3d algorithm\") OR (((\"element means algorithm\") OR (\"neural cosine algorithm\"))))".
• Removing quotes may allow a broader search: (( implement cc3d algorithm ) OR ((( element means algorithm ) OR ( neural cosine algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement cc3d algorithm") OR ((("element means algorithm") OR ("neural cosine algorithm"))))*.
