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)
"movement data algorithm" » "movement data algorithms" (Expand Search), "movement update algorithm" (Expand Search), "movement each 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: (((("movement data algorithm") OR ("present model algorithm"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"movement data algorithm\") OR (\"present model algorithm\"))) OR (\"element sampling algorithm\"))*".
• Removing quotes may allow a broader search: (((( movement data algorithm ) OR ( present model algorithm ))) OR ( element sampling algorithm ))*.
