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)
"relevant data algorithms" » "relevant art algorithms" (Expand Search), "relevant all algorithms" (Expand Search), "relevant both algorithms" (Expand Search)
"recent de algorithms" » "recent mdem algorithms" (Expand Search), "recent ml algorithms" (Expand Search), "recent _ algorithms" (Expand Search), "recent ids algorithms" (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: (((("recent de algorithms") OR ("relevant data algorithms"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"recent de algorithms\") OR (\"relevant data algorithms\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( recent de algorithms ) OR ( relevant data algorithms ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("recent de algorithms") OR ("relevant data algorithms"))) OR ("element sampling algorithm"))*.
