Perhaps you should try some spelling variations:
"element sampling algorithm" » "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"recent mining algorithm" » "recent learning algorithm" (Expand Search), "recent means algorithm" (Expand Search), "recent finding algorithm" (Expand Search), "recent findings algorithm" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element em algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element ree algorithm" (Expand Search), "element 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 rf algorithm\"))~".
• Removing quotes may allow a broader search: (((( element sampling algorithm ) OR ( recent mining algorithm ))) OR ( element rf algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element sampling algorithm") OR ("recent mining algorithm"))) OR ("element rf algorithm"))*.
