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