Perhaps you should try some spelling variations:
"fluent modeling algorithm" » "fluent scheduling algorithm" (Expand Search), "agent modeling algorithm" (Expand Search), "event modeling algorithm" (Expand Search)
"select controls algorithm" » "select control algorithm" (Expand Search), "selected controls algorithm" (Expand Search)
"element data algorithm" » "element jaya algorithm" (Expand Search), "element deer algorithm" (Expand Search), "elements data 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 ((("element data algorithm") OR ("select controls algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"fluent modeling algorithm\") OR (((\"element data algorithm\") OR (\"select controls algorithm\"))))".
• Removing quotes may allow a broader search: (( fluent modeling algorithm ) OR ((( element data algorithm ) OR ( select controls algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("fluent modeling algorithm") OR ((("element data algorithm") OR ("select controls algorithm"))))*.
