Perhaps you should try some spelling variations:
"element learning algorithm" » "element learning algorithms" (Expand Search), "excellent learning algorithm" (Expand Search), "student learning algorithm" (Expand Search), "agent learning algorithm" (Expand Search)
"per aspect algorithm" » "per apdca algorithm" (Expand Search), "per pelt algorithm" (Expand Search), "per spt algorithm" (Expand Search), "qer aspect algorithm" (Expand Search), "every aspect algorithm" (Expand Search)
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding 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: (("per aspect algorithm") OR ((("element learning algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"per aspect algorithm\") OR (((\"element learning algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( per aspect algorithm ) OR ((( element learning algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("per aspect algorithm") OR ((("element learning algorithm") OR ("neural coding algorithm"))))*.
