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