Perhaps you should try some spelling variations:
"fluent modeling algorithm" » "fluent making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "forest modeling algorithm" (Expand Search), "plant modeling algorithm" (Expand Search)
"present data algorithms" » "present art algorithms" (Expand Search), "present all algorithms" (Expand Search), "present both algorithms" (Expand Search), "presence data algorithms" (Expand Search), "present day algorithms" (Expand Search), "recent data algorithms" (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: (("fluent modeling algorithm") OR ((("present data algorithms") OR ("element based algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"fluent modeling algorithm\") OR (((\"present data algorithms\") OR (\"element based algorithm\"))))".
• Removing quotes may allow a broader search: (( fluent modeling algorithm ) OR ((( present data algorithms ) OR ( element based algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("fluent modeling algorithm") OR ((("present data algorithms") OR ("element based algorithm"))))*.
