Perhaps you should try some spelling variations:
"sampling algorithmssssss" » "sampling algorithms" (Expand Search), "sampling algorithmsssssss" (Expand Search)
"sampling algorithmssssssssssic" » "sampling algorithmsssssic" (Expand Search), "sampling algorithmsssssssssssic" (Expand Search)
"sampling algorithm" » "sampling algorithms" (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: "((\"sampling algorithm\") OR (((\"sampling algorithmssssss\") OR (\"sampling algorithmssssssssssic\"))))~".
• Removing quotes may allow a broader search: (( sampling algorithm ) OR ((( sampling algorithmssssss ) OR ( sampling algorithmssssssssssic ))))~.
• Adding a wildcard symbol may retrieve word variants: (("sampling algorithm") OR ((("sampling algorithmssssss") OR ("sampling algorithmssssssssssic"))))*.
