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)
"elements method algorithm" » "elements network algorithm" (Expand Search), "elements means algorithm" (Expand Search), "elements mean algorithm" (Expand Search), "element method algorithm" (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: (("elements method algorithm") OR ((("deep clustering algorithm") OR ("case modeling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements method algorithm\") OR (((\"deep clustering algorithm\") OR (\"case modeling algorithm\"))))".
• Removing quotes may allow a broader search: (( elements method algorithm ) OR ((( deep clustering algorithm ) OR ( case modeling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements method algorithm") OR ((("deep clustering algorithm") OR ("case modeling algorithm"))))*.
