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