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