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