Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element cnn algorithm" » "element _ algorithm" (Expand Search), "element new algorithm" (Expand Search), "element em algorithm" (Expand Search)
"elements ml algorithms" » "elements _ algorithms" (Expand Search), "elements _ algorithm" (Expand Search), "elements b algorithms" (Expand Search), "elements wt algorithms" (Expand Search)

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

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