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