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 method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"elements seu algorithm" » "elements new algorithm" (Expand Search), "elements em algorithm" (Expand Search), "elements svm algorithm" (Expand Search), "elements fe algorithm" (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 ((("elements seu algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement routine algorithm\") OR (((\"elements seu algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( implement routine algorithm ) OR ((( elements seu algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement routine algorithm") OR ((("elements seu algorithm") OR ("element method algorithm"))))*.
