Perhaps you should try some spelling variations:
"improvements using algorithms" » "improvements cosine algorithm" (Expand Search), "improvement using algorithms" (Expand Search)
"element rl algorithm" » "element rd algorithm" (Expand Search), "element carlo algorithm" (Expand Search), "element _ algorithms" (Expand Search), "elements rl algorithm" (Expand Search)
"neural finding algorithm" » "neural findings 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 rl algorithm") OR ("neural finding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"improvements using algorithms\") OR (((\"element rl algorithm\") OR (\"neural finding algorithm\"))))".
• Removing quotes may allow a broader search: (( improvements using algorithms ) OR ((( element rl algorithm ) OR ( neural finding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("improvements using algorithms") OR ((("element rl algorithm") OR ("neural finding algorithm"))))*.
