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 based algorithm" » "event based algorithm" (Expand Search)
"element td3 algorithm" » "element rd algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement routine algorithm\") OR (((\"element based algorithm\") OR (\"element td3 algorithm\"))))~".
• Removing quotes may allow a broader search: (( implement routine algorithm ) OR ((( element based algorithm ) OR ( element td3 algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("implement routine algorithm") OR ((("element based algorithm") OR ("element td3 algorithm"))))*.
