Perhaps you should try some spelling variations:
"elements learning algorithm" » "elements learning algorithms" (Expand Search), "students learning algorithm" (Expand Search), "elements during algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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: (("elements learning algorithm") OR ((("element data algorithm") OR ("element method algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements learning algorithm\") OR (((\"element data algorithm\") OR (\"element method algorithm\"))))".
• Removing quotes may allow a broader search: (( elements learning algorithm ) OR ((( element data algorithm ) OR ( element method algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements learning algorithm") OR ((("element data algorithm") OR ("element method algorithm"))))*.
