Perhaps you should try some spelling variations:
"element based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"element forest algorithm" » "element ore 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: (((("relevant data algorithm") OR ("element based algorithms"))) OR ("element forest algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"relevant data algorithm\") OR (\"element based algorithms\"))) OR (\"element forest algorithm\"))".
• Removing quotes may allow a broader search: (((( relevant data algorithm ) OR ( element based algorithms ))) OR ( element forest algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("relevant data algorithm") OR ("element based algorithms"))) OR ("element forest algorithm"))*.
