Perhaps you should try some spelling variations:
"implement learning algorithm" » "implement learning algorithms" (Expand Search), "implemented learning algorithm" (Expand Search), "implementing learning algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"element fbe algorithm" » "element deer algorithm" (Expand Search), "element rd algorithm" (Expand Search), "elements fbe 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: (("implement learning algorithm") OR ((("element fbe algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement learning algorithm\") OR (((\"element fbe algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( implement learning algorithm ) OR ((( element fbe algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement learning algorithm") OR ((("element fbe algorithm") OR ("element method algorithm"))))*.
