Perhaps you should try some spelling variations:
"time clustering algorithm" » "type clustering algorithm" (Expand Search), "some clustering algorithm" (Expand Search), "tree 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)
"data finding algorithm" » "path finding algorithm" (Expand Search), "data fitting algorithm" (Expand Search), "case finding 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 finding algorithm") OR ("time clustering algorithm"))) OR ("element data algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"data finding algorithm\") OR (\"time clustering algorithm\"))) OR (\"element data algorithm\"))".
• Removing quotes may allow a broader search: (((( data finding algorithm ) OR ( time clustering algorithm ))) OR ( element data algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("data finding algorithm") OR ("time clustering algorithm"))) OR ("element data algorithm"))*.
