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