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