Perhaps you should try some spelling variations:
"element sampling algorithm" » "element scheduling algorithm" (Expand Search)
"element method algorithm" » "element mould algorithm" (Expand Search)
"elements ii algorithm" » "elements rd algorithm" (Expand Search), "elements _ algorithms" (Expand Search), "elements _ 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 sampling algorithm\") OR (((\"elements ii algorithm\") OR (\"element method algorithm\"))))~".
• Removing quotes may allow a broader search: (( element sampling algorithm ) OR ((( elements ii algorithm ) OR ( element method algorithm ))))~.
• Adding a wildcard symbol may retrieve word variants: (("element sampling algorithm") OR ((("elements ii algorithm") OR ("element method algorithm"))))*.
