Perhaps you should try some spelling variations:
"complex functions algorithm" » "complex auction algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"element best algorithm" » "element deer algorithm" (Expand Search), "elements best 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: "((\"complex functions algorithm\") OR (((\"element best algorithm\") OR (\"neural coding algorithm\"))))~".
• Removing quotes may allow a broader search: (( complex functions algorithm ) OR ((( element best algorithm ) OR ( neural coding algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("complex functions algorithm") OR ((("element best algorithm") OR ("neural coding algorithm"))))*.
