Perhaps you should try some spelling variations:
"agent learning algorithm" » "agent learning algorithms" (Expand Search), "student learning algorithm" (Expand Search)
"elements mining algorithm" » "elements during algorithm" (Expand Search)
"elements means algorithm" » "elements search algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "elements res algorithm" (Expand Search)

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 ((("elements mining algorithm") OR ("elements means algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"agent learning algorithm\") OR (((\"elements mining algorithm\") OR (\"elements means algorithm\"))))".
• Removing quotes may allow a broader search: (( agent learning algorithm ) OR ((( elements mining algorithm ) OR ( elements means algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("agent learning algorithm") OR ((("elements mining algorithm") OR ("elements means algorithm"))))*.
