Perhaps you should try some spelling variations:
"field modeling algorithm" » "field making algorithm" (Expand Search), "field model algorithm" (Expand Search), "unified modeling algorithm" (Expand Search)
"deep clustering algorithm" » "cell clustering algorithm" (Expand Search), "re clustering algorithm" (Expand Search), "gene clustering algorithm" (Expand Search)
"element based algorithm" » "engagement based 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: (((("deep clustering algorithm") OR ("field modeling algorithm"))) OR ("element based algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"deep clustering algorithm\") OR (\"field modeling algorithm\"))) OR (\"element based algorithm\"))".
• Removing quotes may allow a broader search: (((( deep clustering algorithm ) OR ( field modeling algorithm ))) OR ( element based algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("deep clustering algorithm") OR ("field modeling algorithm"))) OR ("element based algorithm"))*.
