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