Perhaps you should try some spelling variations:
"improvements using algorithms" » "improvements cosine algorithm" (Expand Search), "improvement using algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"element _ algorithm" » "elements _ algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("improvements using algorithms") OR ("element _ algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"improvements using algorithms\") OR (\"element _ algorithm\"))) OR (\"neural coding algorithm\"))*".
• Removing quotes may allow a broader search: (((( improvements using algorithms ) OR ( element _ algorithm ))) OR ( neural coding algorithm ))*.
