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