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 ("element update algorithm"))) OR ("sample using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithm\") OR (\"element update algorithm\"))) OR (\"sample using algorithm\"))*".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( element update algorithm ))) OR ( sample using algorithm ))*.
