Perhaps you should try some spelling variations:
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"sample using algorithm" » "sample cosine algorithm" (Expand Search)
"element update algorithm" » "elements update algorithm" (Expand Search), "element updated 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 method algorithm") OR ((("sample using algorithm") OR ("element update algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element method algorithm\") OR (((\"sample using algorithm\") OR (\"element update algorithm\"))))*".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( sample using algorithm ) OR ( element update algorithm ))))*.
