Perhaps you should try some spelling variations:
"student learning algorithm" » "student learning algorithms" (Expand Search), "students learning 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)
"present data algorithm" » "present data algorithms" (Expand Search), "present update algorithm" (Expand Search), "present atlas algorithm" (Expand Search), "presence data algorithm" (Expand Search), "present day algorithm" (Expand Search), "recent data 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: (("student learning algorithm") OR ((("element mesh algorithm") OR ("present data algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"student learning algorithm\") OR (((\"element mesh algorithm\") OR (\"present data algorithm\"))))".
• Removing quotes may allow a broader search: (( student learning algorithm ) OR ((( element mesh algorithm ) OR ( present data algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("student learning algorithm") OR ((("element mesh algorithm") OR ("present data algorithm"))))*.
