Perhaps you should try some spelling variations:
"element learning algorithm" » "element learning algorithms" (Expand Search), "student learning algorithm" (Expand Search)
"present using algorithms" » "present cosine algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling 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: (("element learning algorithm") OR ((("present using algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element learning algorithm\") OR (((\"present using algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element learning algorithm ) OR ((( present using algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element learning algorithm") OR ((("present using algorithms") OR ("neural coding algorithm"))))*.
