Perhaps you should try some spelling variations:
"relevant changes algorithm" » "relevant enhanced algorithm" (Expand Search), "relevant anbs algorithm" (Expand Search), "relevant genes algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh 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 means algorithm") OR ((("relevant changes algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element means algorithm\") OR (((\"relevant changes algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element means algorithm ) OR ((( relevant changes algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element means algorithm") OR ((("relevant changes algorithm") OR ("neural coding algorithm"))))*.
