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)
"elements upon algorithm" » "elements ppo algorithm" (Expand Search), "elements fusion algorithm" (Expand Search), "elements pso algorithm" (Expand Search), "elements ppm algorithm" (Expand Search)
"elements new algorithm" » "elements novel algorithm" (Expand Search), "elements _ algorithm" (Expand Search), "elements ree algorithm" (Expand Search), "elements fe algorithm" (Expand Search), "elements res algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("elements upon algorithm") OR ((("element sampling algorithm") OR ("elements new algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements upon algorithm\") OR (((\"element sampling algorithm\") OR (\"elements new algorithm\"))))".
• Removing quotes may allow a broader search: (( elements upon algorithm ) OR ((( element sampling algorithm ) OR ( elements new algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements upon algorithm") OR ((("element sampling algorithm") OR ("elements new algorithm"))))*.
