Perhaps you should try some spelling variations:
"agent learning algorithm" » "agent learning algorithms" (Expand Search), "student learning algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te 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 mesh algorithm") OR ((("agent learning algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element mesh algorithm\") OR (((\"agent learning algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( element mesh algorithm ) OR ((( agent learning algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element mesh algorithm") OR ((("agent learning algorithm") OR ("element method algorithm"))))*.
