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