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)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"present both algorithms" » "present art algorithms" (Expand Search), "present four algorithms" (Expand Search), "present box algorithm" (Expand Search), "present work algorithms" (Expand Search), "present high algorithms" (Expand Search), "present data 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: (("present both algorithms") OR ((("implement routine algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present both algorithms\") OR (((\"implement routine algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( present both algorithms ) OR ((( implement routine algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("present both algorithms") OR ((("implement routine algorithm") OR ("neural coding algorithm"))))*.
