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 fe algorithm" » "elements new algorithm" (Expand Search), "elements de algorithms" (Expand Search), "elements seu algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "element te algorithm" (Expand Search), "elements b 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 ("elements fe algorithm"))) OR ("agent learning algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"elements fe algorithm\"))) OR (\"agent learning algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( elements fe algorithm ))) OR ( agent learning algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("elements fe algorithm"))) OR ("agent learning algorithm"))*.
