Perhaps you should try some spelling variations:
"elements sampling algorithm" » "elements making algorithm" (Expand Search), "elements modeling algorithm" (Expand Search), "elements mining algorithm" (Expand Search), "client sampling algorithm" (Expand Search), "sediment 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 box algorithm" » "element best algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search)

Try widening your search to All Fields.

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 ("element box algorithm"))) OR ("elements sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element cnn algorithm\") OR (\"element box algorithm\"))) OR (\"elements sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element cnn algorithm ) OR ( element box algorithm ))) OR ( elements sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element cnn algorithm") OR ("element box algorithm"))) OR ("elements sampling algorithm"))*.
