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)
"event based algorithm" » "agent based algorithm" (Expand Search), "levels based algorithm" (Expand Search), "effect based 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: (("event based algorithm") OR ((("implement routine algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"event based algorithm\") OR (((\"implement routine algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( event based algorithm ) OR ((( implement routine algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("event based algorithm") OR ((("implement routine algorithm") OR ("neural coding algorithm"))))*.
