Perhaps you should try some spelling variations:
"alexnet learning algorithm" » "alexnet learning algorithms" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural colony algorithm" (Expand Search), "neural scheduling algorithm" (Expand Search)
"element tide algorithm" » "element rd algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements tide 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 tide algorithm") OR ((("alexnet learning algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element tide algorithm\") OR (((\"alexnet learning algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( element tide algorithm ) OR ((( alexnet learning algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element tide algorithm") OR ((("alexnet learning algorithm") OR ("neural coding algorithm"))))*.
