Perhaps you should try some spelling variations:
"system modeling algorithm" » "system making algorithm" (Expand Search), "system model algorithm" (Expand Search), "system models algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element based algorithm" » "engagement based 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 (\"element based algorithm\"))) OR (\"system modeling algorithm\"))~".
• Removing quotes may allow a broader search: (((( element method algorithm ) OR ( element based algorithm ))) OR ( system modeling algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element method algorithm") OR ("element based algorithm"))) OR ("system modeling algorithm"))*.
