Perhaps you should try some spelling variations:
"case modeling algorithm" » "case scheduling algorithm" (Expand Search), "based modeling algorithm" (Expand Search)
"data sorting algorithms" » "data learning algorithms" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)

You may be able to get more results by adjusting your search query.

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