Perhaps you should try some spelling variations:
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (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.

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