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)
"level routing algorithm" » "level modeling algorithm" (Expand Search), "level finding algorithm" (Expand Search), "level making algorithm" (Expand Search), "level coupling algorithm" (Expand Search), "level using algorithm" (Expand Search), "level coding 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: (("level routing algorithm") OR ((("element learning algorithm") OR ("neural coding algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"level routing algorithm\") OR (((\"element learning algorithm\") OR (\"neural coding algorithm\"))))".
• Removing quotes may allow a broader search: (( level routing algorithm ) OR ((( element learning algorithm ) OR ( neural coding algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("level routing algorithm") OR ((("element learning algorithm") OR ("neural coding algorithm"))))*.
