Perhaps you should try some spelling variations:
"element mapping algorithms" » "element matching algorithms" (Expand Search), "element making algorithm" (Expand Search), "element pacing algorithms" (Expand Search), "elemental mapping algorithms" (Expand Search), "element modeling algorithms" (Expand Search), "argument mapping algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both 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: (("relevant data algorithms") OR ((("element mapping algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"relevant data algorithms\") OR (((\"element mapping algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( relevant data algorithms ) OR ((( element mapping algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("relevant data algorithms") OR ((("element mapping algorithms") OR ("neural coding algorithm"))))*.
