Perhaps you should try some spelling variations:
"element sampling algorithm" » "element scheduling algorithm" (Expand Search), "elements sampling algorithm" (Expand Search)
"recent mining algorithm" » "recent cosine algorithm" (Expand Search)
"element ore algorithm" » "element rd algorithm" (Expand Search), "element deer algorithm" (Expand Search), "element cosine algorithm" (Expand Search), "elements ore 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: "((((\"element sampling algorithm\") OR (\"recent mining algorithm\"))) OR (\"element ore algorithm\"))~".
• Removing quotes may allow a broader search: (((( element sampling algorithm ) OR ( recent mining algorithm ))) OR ( element ore algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element sampling algorithm") OR ("recent mining algorithm"))) OR ("element ore algorithm"))*.
