Perhaps you should try some spelling variations:
"implement modeling algorithm" » "implement scheduling algorithm" (Expand Search), "implemented modeling algorithm" (Expand Search), "implementing modeling algorithm" (Expand Search)
"element means algorithm" » "element search algorithm" (Expand Search), "elements means 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: (("implement modeling algorithm") OR ((("element data algorithm") OR ("element means algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"implement modeling algorithm\") OR (((\"element data algorithm\") OR (\"element means algorithm\"))))".
• Removing quotes may allow a broader search: (( implement modeling algorithm ) OR ((( element data algorithm ) OR ( element means algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("implement modeling algorithm") OR ((("element data algorithm") OR ("element means algorithm"))))*.
