Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement cosine algorithm" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh algorithm" (Expand Search)
"present update algorithm" » "present updated 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: (((("element mesh algorithm") OR ("present update algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mesh algorithm\") OR (\"present update algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( element mesh algorithm ) OR ( present update algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mesh algorithm") OR ("present update algorithm"))) OR ("implement routine algorithm"))*.
