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)
"effects forest algorithm" » "effects test 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 learning algorithm") OR ("element means algorithm"))) OR ("effects forest algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element learning algorithm\") OR (\"element means algorithm\"))) OR (\"effects forest algorithm\"))".
• Removing quotes may allow a broader search: (((( element learning algorithm ) OR ( element means algorithm ))) OR ( effects forest algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element learning algorithm") OR ("element means algorithm"))) OR ("effects forest algorithm"))*.
