Perhaps you should try some spelling variations:
"implement routine algorithm" » "implement cosine algorithm" (Expand Search)
"element cc3d algorithm" » "element rd algorithm" (Expand Search), "elements cc3d algorithm" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh 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 cc3d algorithm") OR ((("implement routine algorithm") OR ("element mesh algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element cc3d algorithm\") OR (((\"implement routine algorithm\") OR (\"element mesh algorithm\"))))".
• Removing quotes may allow a broader search: (( element cc3d algorithm ) OR ((( implement routine algorithm ) OR ( element mesh algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element cc3d algorithm") OR ((("implement routine algorithm") OR ("element mesh algorithm"))))*.
