Perhaps you should try some spelling variations:
"elements sampling algorithm" » "elements mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"present forest algorithm" » "present free algorithm" (Expand Search)
"elements res algorithm" » "elements best algorithm" (Expand Search), "elements rast algorithm" (Expand Search), "elements new algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "elements ices 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: (((("elements res algorithm") OR ("present forest algorithm"))) OR ("elements sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements res algorithm\") OR (\"present forest algorithm\"))) OR (\"elements sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements res algorithm ) OR ( present forest algorithm ))) OR ( elements sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements res algorithm") OR ("present forest algorithm"))) OR ("elements sampling algorithm"))*.
