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