Perhaps you should try some spelling variations:
"joint modeling algorithm" » "joint making algorithm" (Expand Search), "joint model algorithm" (Expand Search)
"element custom algorithm" » "element fusion algorithm" (Expand Search), "element control algorithm" (Expand Search), "element lasso 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: (((("joint modeling algorithm") OR ("data clustering algorithm"))) OR ("element custom algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"joint modeling algorithm\") OR (\"data clustering algorithm\"))) OR (\"element custom algorithm\"))".
• Removing quotes may allow a broader search: (((( joint modeling algorithm ) OR ( data clustering algorithm ))) OR ( element custom algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("joint modeling algorithm") OR ("data clustering algorithm"))) OR ("element custom algorithm"))*.
