Perhaps you should try some spelling variations:
"case modeling algorithm" » "case scheduling algorithm" (Expand Search), "based modeling algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search), "elements method algorithm" (Expand Search)
"data tracking algorithm" » "radar tracking 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: "((\"element method algorithm\") OR (((\"data tracking algorithm\") OR (\"case modeling algorithm\"))))~".
• Removing quotes may allow a broader search: (( element method algorithm ) OR ((( data tracking algorithm ) OR ( case modeling algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("element method algorithm") OR ((("data tracking algorithm") OR ("case modeling algorithm"))))*.
