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