Perhaps you should try some spelling variations:
"element sampling algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "client sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"element model algorithm" » "element novel algorithm" (Expand Search), "element modbo algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"present model algorithm" » "present novel algorithm" (Expand Search), "present modbo algorithm" (Expand Search), "present modeling algorithm" (Expand Search), "rodent model 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: "((((\"element model algorithm\") OR (\"present model algorithm\"))) OR (\"element sampling algorithm\"))~".
• Removing quotes may allow a broader search: (((( element model algorithm ) OR ( present model algorithm ))) OR ( element sampling algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element model algorithm") OR ("present model algorithm"))) OR ("element sampling algorithm"))*.
