Perhaps you should try some spelling variations:
"element sampling algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "client sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"element cnn algorithm" » "element mean algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search)
"element gnb algorithm" » "element mnb algorithm" (Expand Search), "element anbs algorithm" (Expand Search), "element b algorithm" (Expand Search), "element g 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 cnn algorithm\") OR (\"element gnb algorithm\"))) OR (\"element sampling algorithm\"))~".
• Removing quotes may allow a broader search: (((( element cnn algorithm ) OR ( element gnb algorithm ))) OR ( element sampling algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("element cnn algorithm") OR ("element gnb algorithm"))) OR ("element sampling algorithm"))*.
