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