Perhaps you should try some spelling variations:
"element means algorithm" » "element search algorithm" (Expand Search), "element mesh algorithm" (Expand Search)
"present study algorithm" » "present wsindy algorithm" (Expand Search), "present td3 algorithm" (Expand Search), "present seu algorithm" (Expand Search)
"data using algorithm" » "data using algorithms" (Expand Search), "data routing algorithm" (Expand Search), "data fusion algorithm" (Expand Search)

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

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