Perhaps you should try some spelling variations:
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"experimental ir algorithm" » "experimental nmr algorithm" (Expand Search), "experimental _ algorithm" (Expand Search), "experimental hs algorithm" (Expand Search), "experimental ii algorithm" (Expand Search), "experimental lr algorithm" (Expand Search), "experimental iii algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh 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: (((("experimental ir algorithm") OR ("element means algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"experimental ir algorithm\") OR (\"element means algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( experimental ir algorithm ) OR ( element means algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("experimental ir algorithm") OR ("element means algorithm"))) OR ("neural coding algorithm"))*.
