Perhaps you should try some spelling variations:
"case modeling algorithm" » "case scheduling algorithm" (Expand Search), "based modeling algorithm" (Expand Search)
"element method algorithms" » "elements method algorithms" (Expand Search), "element methods algorithms" (Expand Search)
"present update algorithm" » "present updated algorithm" (Expand Search)

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 algorithms") OR ("present update algorithm"))) OR ("case modeling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element method algorithms\") OR (\"present update algorithm\"))) OR (\"case modeling algorithm\"))".
• Removing quotes may allow a broader search: (((( element method algorithms ) OR ( present update algorithm ))) OR ( case modeling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithms") OR ("present update algorithm"))) OR ("case modeling algorithm"))*.
