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