Perhaps you should try some spelling variations:
"student learning algorithm" » "student learning algorithms" (Expand Search)
"element sampling algorithm" » "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"element new algorithm" » "element novel algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element te algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element mesh 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 sampling algorithm"))) OR ("element new algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"student learning algorithm\") OR (\"element sampling algorithm\"))) OR (\"element new algorithm\"))".
• Removing quotes may allow a broader search: (((( student learning algorithm ) OR ( element sampling algorithm ))) OR ( element new algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("student learning algorithm") OR ("element sampling algorithm"))) OR ("element new algorithm"))*.
