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