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)
"movement cnn algorithm" » "movement rd algorithm" (Expand Search), "movement colony algorithm" (Expand Search), "movement 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: (("movement cnn algorithm") OR ((("implement routine algorithm") OR ("level using algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"movement cnn algorithm\") OR (((\"implement routine algorithm\") OR (\"level using algorithm\"))))".
• Removing quotes may allow a broader search: (( movement cnn algorithm ) OR ((( implement routine algorithm ) OR ( level using algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("movement cnn algorithm") OR ((("implement routine algorithm") OR ("level using algorithm"))))*.
