Perhaps you should try some spelling variations:
"agent learning algorithm" » "agent learning algorithms" (Expand Search), "student learning algorithm" (Expand Search)
"neural codingn_ algorithm" » "neural cosine algorithm" (Expand Search), "neural coding algorithm" (Expand Search)
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data 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 ((("agent learning algorithm") OR ("neural codingn_ algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element update algorithm\") OR (((\"agent learning algorithm\") OR (\"neural codingn_ algorithm\"))))".
• Removing quotes may allow a broader search: (( element update algorithm ) OR ((( agent learning algorithm ) OR ( neural codingn_ algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element update algorithm") OR ((("agent learning algorithm") OR ("neural codingn_ algorithm"))))*.
