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)
"present model algorithm" » "present novel algorithm" (Expand Search), "present forest algorithm" (Expand Search), "element model algorithm" (Expand Search), "rodent model algorithm" (Expand Search)
"elements ree algorithm" » "elements tree algorithms" (Expand Search), "elements new algorithm" (Expand Search), "elements em algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements present algorithm" (Expand Search), "elements related 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: "((\"elements ree algorithm\") OR (((\"element sampling algorithm\") OR (\"present model algorithm\"))))~".
• Removing quotes may allow a broader search: (( elements ree algorithm ) OR ((( element sampling algorithm ) OR ( present model algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("elements ree algorithm") OR ((("element sampling algorithm") OR ("present model algorithm"))))*.
