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