Perhaps you should try some spelling variations:
"element sampling algorithm" » "element scheduling algorithm" (Expand Search), "elements sampling algorithm" (Expand Search)
"relevant data algorithm" » "relevant jaya algorithm" (Expand Search), "relevant deer algorithm" (Expand Search)
"element fbe algorithm" » "element deer algorithm" (Expand Search), "element rd algorithm" (Expand Search), "elements fbe 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: (((("element fbe algorithm") OR ("relevant data algorithm"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element fbe algorithm\") OR (\"relevant data algorithm\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element fbe algorithm ) OR ( relevant data algorithm ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element fbe algorithm") OR ("relevant data algorithm"))) OR ("element sampling algorithm"))*.
