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 data algorithms" » "element jaya algorithm" (Expand Search), "elements data algorithms" (Expand Search)
"element mesh algorithm" » "element deer algorithm" (Expand Search), "element search algorithm" (Expand Search), "elements mesh 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 data algorithms") OR ("element mesh algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement learning algorithm\") OR (((\"element data algorithms\") OR (\"element mesh algorithm\"))))".
• Removing quotes may allow a broader search: (( implement learning algorithm ) OR ((( element data algorithms ) OR ( element mesh algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement learning algorithm") OR ((("element data algorithms") OR ("element mesh algorithm"))))*.
