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