Perhaps you should try some spelling variations:
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (Expand Search)
"based mining algorithm" » "based finding algorithm" (Expand Search), "based making algorithm" (Expand Search), "based training algorithms" (Expand Search), "based binding algorithm" (Expand Search), "based training algorithm" (Expand Search), "based imaging algorithm" (Expand Search)
"data clustering algorithm" » "deep clustering algorithm" (Expand Search), "spatial clustering algorithm" (Expand Search), "dbscan clustering 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 method algorithm") OR ((("data clustering algorithm") OR ("based mining algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"data clustering algorithm\") OR (\"based mining algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( data clustering algorithm ) OR ( based mining algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("data clustering algorithm") OR ("based mining algorithm"))))*.
