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)
"event three algorithms" » "event forest algorithms" (Expand Search), "event based algorithms" (Expand Search), "event art algorithms" (Expand Search), "even three algorithms" (Expand Search), "event free algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding 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 three algorithms") OR ((("implement routine algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"event three algorithms\") OR (((\"implement routine algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( event three algorithms ) OR ((( implement routine algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("event three algorithms") OR ((("implement routine algorithm") OR ("neural coding algorithm"))))*.
