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)
"elements based algorithm" » "experiments based algorithm" (Expand Search), "elements related algorithm" (Expand Search)
"elements cnn algorithm" » "elements mean algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements crcy algorithm" (Expand Search), "elements ices algorithm" (Expand Search), "elements upon 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: (((("elements cnn algorithm") OR ("elements based algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements cnn algorithm\") OR (\"elements based algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( elements cnn algorithm ) OR ( elements based algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements cnn algorithm") OR ("elements based algorithm"))) OR ("implement routine algorithm"))*.
