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