Perhaps you should try some spelling variations:
"implement routing algorithm" » "implement routine algorithm" (Expand Search), "implement modeling algorithm" (Expand Search), "implement finding algorithm" (Expand Search), "implement making algorithm" (Expand Search)
"present study algorithm" » "present wsindy algorithm" (Expand Search), "present td3 algorithm" (Expand Search), "present seu algorithm" (Expand Search)
"element based algorithm" » "engagement based 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 routing algorithm") OR ((("element based algorithm") OR ("present study algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement routing algorithm\") OR (((\"element based algorithm\") OR (\"present study algorithm\"))))".
• Removing quotes may allow a broader search: (( implement routing algorithm ) OR ((( element based algorithm ) OR ( present study algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement routing algorithm") OR ((("element based algorithm") OR ("present study algorithm"))))*.
