Perhaps you should try some spelling variations:
"curve learning algorithm" » "curve learning algorithms" (Expand Search), "core learning algorithm" (Expand Search), "current learning algorithm" (Expand Search), "active learning algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding 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 method algorithm") OR ((("curve learning algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"curve learning algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( curve learning algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("curve learning algorithm") OR ("neural coding algorithm"))))*.
