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 tide algorithm" » "element td3 algorithm" (Expand Search), "element leiden algorithm" (Expand Search), "element five algorithms" (Expand Search), "element te algorithm" (Expand Search), "element model algorithm" (Expand Search), "element citre algorithm" (Expand Search)
"element study algorithm" » "present study algorithm" (Expand Search), "recent study algorithm" (Expand Search), "event study 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 study algorithm") OR ("element tide algorithm"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element study algorithm\") OR (\"element tide algorithm\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element study algorithm ) OR ( element tide algorithm ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element study algorithm") OR ("element tide algorithm"))) OR ("element sampling algorithm"))*.
