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 mean algorithm" (Expand Search)
"effects a algorithm" » "effects _ algorithm" (Expand Search), "effects b algorithm" (Expand Search), "effects _ algorithms" (Expand Search), "effects i 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 a algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element sampling algorithm\") OR (\"element method algorithm\"))) OR (\"effects a algorithm\"))".
• Removing quotes may allow a broader search: (((( element sampling algorithm ) OR ( element method algorithm ))) OR ( effects a algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element sampling algorithm") OR ("element method algorithm"))) OR ("effects a algorithm"))*.
