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 meshs algorithm" » "element means algorithm" (Expand Search), "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element mesh 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 ((("agent learning algorithm") OR ("element meshs algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"agent learning algorithm\") OR (\"element meshs algorithm\"))))".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( agent learning algorithm ) OR ( element meshs algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("agent learning algorithm") OR ("element meshs algorithm"))))*.
