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 network algorithm" » "element new algorithm" (Expand Search), "alignment network algorithm" (Expand Search)
"element based algorithm" » "engagement based algorithm" (Expand Search)

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("system modeling algorithm") OR ((("element network algorithm") OR ("element based algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"system modeling algorithm\") OR (((\"element network algorithm\") OR (\"element based algorithm\"))))".
• Removing quotes may allow a broader search: (( system modeling algorithm ) OR ((( element network algorithm ) OR ( element based algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("system modeling algorithm") OR ((("element network algorithm") OR ("element based algorithm"))))*.
