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)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant de algorithms" (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: (((("element sampling algorithm") OR ("recent mining algorithm"))) OR ("relevant data algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element sampling algorithm\") OR (\"recent mining algorithm\"))) OR (\"relevant data algorithms\"))".
• Removing quotes may allow a broader search: (((( element sampling algorithm ) OR ( recent mining algorithm ))) OR ( relevant data algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("element sampling algorithm") OR ("recent mining algorithm"))) OR ("relevant data algorithms"))*.
