Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement cosine algorithm" (Expand Search)
"recent data algorithm" » "recent jaya algorithm" (Expand Search), "recent deer algorithm" (Expand Search)
"element mean algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mean algorithm" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("recent data algorithm") OR ((("implement routine algorithm") OR ("element mean algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"recent data algorithm\") OR (((\"implement routine algorithm\") OR (\"element mean algorithm\"))))".
• Removing quotes may allow a broader search: (( recent data algorithm ) OR ((( implement routine algorithm ) OR ( element mean algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("recent data algorithm") OR ((("implement routine algorithm") OR ("element mean algorithm"))))*.
