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 abs algorithm" » "element jaya algorithm" (Expand Search), "element rd algorithm" (Expand Search), "elements abs 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: (("improvements using algorithms") OR ((("element abs algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"improvements using algorithms\") OR (((\"element abs algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( improvements using algorithms ) OR ((( element abs algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("improvements using algorithms") OR ((("element abs algorithm") OR ("neural coding algorithm"))))*.
