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