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)
"elements tree algorithms" » "elements three algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res algorithms" (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 ("element method algorithm"))) OR ("elements tree algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"agent learning algorithm\") OR (\"element method algorithm\"))) OR (\"elements tree algorithms\"))".
• Removing quotes may allow a broader search: (((( agent learning algorithm ) OR ( element method algorithm ))) OR ( elements tree algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("agent learning algorithm") OR ("element method algorithm"))) OR ("elements tree algorithms"))*.
