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