Perhaps you should try some spelling variations:
"cloud learning algorithm" » "cloud learning algorithms" (Expand Search), "word learning algorithm" (Expand Search), "long learning algorithm" (Expand Search), "core learning algorithm" (Expand Search)
"element method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (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: (("cloud learning algorithm") OR ((("element data algorithm") OR ("element method algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"cloud learning algorithm\") OR (((\"element data algorithm\") OR (\"element method algorithms\"))))".
• Removing quotes may allow a broader search: (( cloud learning algorithm ) OR ((( element data algorithm ) OR ( element method algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("cloud learning algorithm") OR ((("element data algorithm") OR ("element method algorithms"))))*.
