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)
"element cc3d algorithm" » "element cscap algorithm" (Expand Search), "element cnn algorithm" (Expand Search), "element wold algorithm" (Expand Search), "elements cc3d algorithm" (Expand Search)
"relevant data algorithm" » "relevant data algorithms" (Expand Search), "relevant update algorithm" (Expand Search), "relevant atlas 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 ("relevant data algorithm"))) OR ("implement routine algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cc3d algorithm\") OR (\"relevant data algorithm\"))) OR (\"implement routine algorithm\"))".
• Removing quotes may allow a broader search: (((( element cc3d algorithm ) OR ( relevant data algorithm ))) OR ( implement routine algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element cc3d algorithm") OR ("relevant data algorithm"))) OR ("implement routine algorithm"))*.
