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