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), "elements mapping algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element ore algorithm" » "element rf algorithm" (Expand Search), "element rl algorithm" (Expand Search), "element erf algorithm" (Expand Search), "element te algorithm" (Expand Search), "element fbe algorithm" (Expand Search), "element ree 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 ore algorithm") OR ((("elemental mapping algorithms") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element ore algorithm\") OR (((\"elemental mapping algorithms\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element ore algorithm ) OR ((( elemental mapping algorithms ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element ore algorithm") OR ((("elemental mapping algorithms") OR ("neural coding algorithm"))))*.
