Perhaps you should try some spelling variations:
"element update algorithm" » "element pass algorithm" (Expand Search), "element data algorithms" (Expand Search), "element ipca algorithm" (Expand Search), "element data algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"present study algorithm" » "present wsindy algorithm" (Expand Search), "present td3 algorithm" (Expand Search), "present seu 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: (((("present study algorithm") OR ("element update algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present study algorithm\") OR (\"element update algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( present study algorithm ) OR ( element update algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("present study algorithm") OR ("element update algorithm"))) OR ("neural coding algorithm"))*.
