Perhaps you should try some spelling variations:
"improvements making algorithm" » "improvements make algorithm" (Expand Search), "improvements using algorithm" (Expand Search), "improvement among algorithm" (Expand Search), "improvements learning algorithm" (Expand Search), "improvements finding algorithm" (Expand Search), "improvements means algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element ml algorithms" » "element _ algorithms" (Expand Search), "element g algorithms" (Expand Search), "element te 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: (("improvements making algorithm") OR ((("element ml algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"improvements making algorithm\") OR (((\"element ml algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( improvements making algorithm ) OR ((( element ml algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("improvements making algorithm") OR ((("element ml algorithms") OR ("neural coding algorithm"))))*.
