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