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