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