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: (("present update algorithm") OR ((("implement routine algorithm") OR ("element mesh algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present update algorithm\") OR (((\"implement routine algorithm\") OR (\"element mesh algorithm\"))))".
• Removing quotes may allow a broader search: (( present update algorithm ) OR ((( implement routine algorithm ) OR ( element mesh algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present update algorithm") OR ((("implement routine algorithm") OR ("element mesh algorithm"))))*.
