Perhaps you should try some spelling variations:
"element mappingnb algorithm" » "element making algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search)
"neural codingnb algorithm" » "neural cosine algorithm" (Expand Search), "neural coding algorithm" (Expand Search)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ 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: (("element g algorithm") OR ((("element mappingnb algorithm") OR ("neural codingnb algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element g algorithm\") OR (((\"element mappingnb algorithm\") OR (\"neural codingnb algorithm\"))))".
• Removing quotes may allow a broader search: (( element g algorithm ) OR ((( element mappingnb algorithm ) OR ( neural codingnb algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element g algorithm") OR ((("element mappingnb algorithm") OR ("neural codingnb algorithm"))))*.
