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