Perhaps you should try some spelling variations:
"severity cosine algorithm" » "severity colony algorithm" (Expand Search), "security cosine algorithm" (Expand Search)
"neural coding algorithm" » "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"element making algorithm" » "elements making algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"severity cosine algorithm\") OR (((\"element making algorithm\") OR (\"neural coding algorithm\"))))~".
• Removing quotes may allow a broader search: (( severity cosine algorithm ) OR ((( element making algorithm ) OR ( neural coding algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("severity cosine algorithm") OR ((("element making algorithm") OR ("neural coding algorithm"))))*.
