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