Perhaps you should try some spelling variations:
"element sampling algorithm" » "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element modbo algorithm" (Expand Search)
"effects mean algorithm" » "effects means algorithm" (Expand Search), "effects new algorithm" (Expand Search), "effects em algorithm" (Expand Search), "effects meta algorithm" (Expand Search), "effect meta algorithm" (Expand Search), "effects via 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: (((("element sampling algorithm") OR ("element method algorithm"))) OR ("effects mean algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element sampling algorithm\") OR (\"element method algorithm\"))) OR (\"effects mean algorithm\"))".
• Removing quotes may allow a broader search: (((( element sampling algorithm ) OR ( element method algorithm ))) OR ( effects mean algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element sampling algorithm") OR ("element method algorithm"))) OR ("effects mean algorithm"))*.
