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)
"level coding algorithm" » "level cosine algorithm" (Expand Search), "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level according algorithm" (Expand Search), "level using algorithm" (Expand Search)
"relevant non algorithm" » "relevant new algorithm" (Expand Search), "relevant box algorithm" (Expand Search), "relevant cnn algorithm" (Expand Search), "relevant role algorithm" (Expand Search), "relevant _ 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 coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant non algorithm\") OR (((\"implement routine algorithm\") OR (\"level coding algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant non algorithm ) OR ((( implement routine algorithm ) OR ( level coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant non algorithm") OR ((("implement routine algorithm") OR ("level coding algorithm"))))*.
