Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement cosine algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "elements means algorithm" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh 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 means algorithm") OR ((("implement routine algorithm") OR ("element mesh algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element means algorithm\") OR (((\"implement routine algorithm\") OR (\"element mesh algorithm\"))))*".
• Removing quotes may allow a broader search: (( element means algorithm ) OR ((( implement routine algorithm ) OR ( element mesh algorithm ))))*.
