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