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), "implemented routine algorithm" (Expand Search), "implementing routine algorithm" (Expand Search)
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion 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: (((("implement routine algorithm") OR ("element update algorithm"))) OR ("data using algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"implement routine algorithm\") OR (\"element update algorithm\"))) OR (\"data using algorithm\"))".
• Removing quotes may allow a broader search: (((( implement routine algorithm ) OR ( element update algorithm ))) OR ( data using algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("implement routine algorithm") OR ("element update algorithm"))) OR ("data using algorithm"))*.
