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