Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement routing algorithm" (Expand Search), "implement cosine algorithm" (Expand Search), "implement retinex algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"recent both algorithms" » "recent art algorithms" (Expand Search), "recent four algorithms" (Expand Search), "recent box 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 both algorithms") OR ((("implement routine algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"recent both algorithms\") OR (((\"implement routine algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( recent both algorithms ) OR ((( implement routine algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("recent both algorithms") OR ((("implement routine algorithm") OR ("element method algorithm"))))*.
