Perhaps you should try some spelling variations:
"element sampling algorithm" » "element scheduling algorithm" (Expand Search), "elements sampling algorithm" (Expand Search)
"present forest algorithm" » "present firefly algorithm" (Expand Search)
"present data algorithm" » "present jaya algorithm" (Expand Search), "present deer 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: (((("present data algorithm") OR ("present forest algorithm"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"present data algorithm\") OR (\"present forest algorithm\"))) OR (\"element sampling algorithm\"))*".
• Removing quotes may allow a broader search: (((( present data algorithm ) OR ( present forest algorithm ))) OR ( element sampling algorithm ))*.
