Perhaps you should try some spelling variations:
"element sampling algorithm" » "element scheduling algorithm" (Expand Search), "elements sampling algorithm" (Expand Search)
"present data algorithm" » "present jaya algorithm" (Expand Search), "present deer algorithm" (Expand Search)
"element search algorithm" » "elements search algorithm" (Expand Search), "element research algorithm" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present data algorithm\") OR (((\"element sampling algorithm\") OR (\"element search algorithm\"))))~".
• Removing quotes may allow a broader search: (( present data algorithm ) OR ((( element sampling algorithm ) OR ( element search algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("present data algorithm") OR ((("element sampling algorithm") OR ("element search algorithm"))))*.
