Perhaps you should try some spelling variations:
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"reference set algorithm" » "reference test algorithm" (Expand Search), "reference data algorithm" (Expand Search), "reference list algorithm" (Expand Search), "reference best algorithm" (Expand Search), "reference new algorithm" (Expand Search), "reference em 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: (("elements method algorithm") OR ((("reference set algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"reference set algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( reference set algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("reference set algorithm") OR ("neural coding algorithm"))))*.
