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