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