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 cnn algorithm" » "element rd algorithm" (Expand Search), "element colony algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements cnn 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 cnn algorithm\"))) OR (\"element sampling algorithm\"))~".
• Removing quotes may allow a broader search: (((( present data algorithm ) OR ( element cnn algorithm ))) OR ( element sampling algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("present data algorithm") OR ("element cnn algorithm"))) OR ("element sampling algorithm"))*.
