Perhaps you should try some spelling variations:
"present learning algorithm" » "present learning algorithms" (Expand Search), "student learning algorithm" (Expand Search), "driven learning algorithm" (Expand Search), "agent learning algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"elements tree algorithms" » "elements three algorithms" (Expand Search), "elements art algorithms" (Expand Search), "elements two algorithms" (Expand Search), "elements ree algorithms" (Expand Search), "element ree algorithms" (Expand Search), "elements res 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: (("elements tree algorithms") OR ((("present learning algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements tree algorithms\") OR (((\"present learning algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( elements tree algorithms ) OR ((( present learning algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements tree algorithms") OR ((("present learning algorithm") OR ("neural coding algorithm"))))*.
