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