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