Perhaps you should try some spelling variations:
"element sampling algorithm" » "element scheduling algorithm" (Expand Search), "elements sampling algorithm" (Expand Search)
"implement making algorithm" » "implement cosine algorithm" (Expand Search)
"element rf algorithm" » "element rd algorithm" (Expand Search), "element _ algorithms" (Expand Search), "elements rf 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 rf algorithm") OR ((("implement making algorithm") OR ("element sampling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element rf algorithm\") OR (((\"implement making algorithm\") OR (\"element sampling algorithm\"))))*".
• Removing quotes may allow a broader search: (( element rf algorithm ) OR ((( implement making algorithm ) OR ( element sampling algorithm ))))*.
