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)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas algorithm" (Expand Search)
"elements rf algorithm" » "elements _ algorithm" (Expand Search), "elements ii algorithm" (Expand Search), "elements art algorithms" (Expand Search), "elements ree algorithm" (Expand Search), "elements res 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 ((("relevant data algorithm") OR ("elements rf algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement routine algorithm\") OR (((\"relevant data algorithm\") OR (\"elements rf algorithm\"))))".
• Removing quotes may allow a broader search: (( implement routine algorithm ) OR ((( relevant data algorithm ) OR ( elements rf algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement routine algorithm") OR ((("relevant data algorithm") OR ("elements rf algorithm"))))*.
