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)
"recent data algorithms" » "recent art algorithms" (Expand Search), "recent all algorithms" (Expand Search), "recent both algorithms" (Expand Search), "relevant data algorithms" (Expand Search)
"relevant de algorithms" » "relevant mdem algorithms" (Expand Search), "relevant ml algorithms" (Expand Search), "relevant _ algorithms" (Expand Search), "relevant 3d algorithms" (Expand Search), "relevant mh 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 data algorithms") OR ("relevant de algorithms"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"recent data algorithms\") OR (\"relevant de algorithms\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( recent data algorithms ) OR ( relevant de algorithms ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("recent data algorithms") OR ("relevant de algorithms"))) OR ("element sampling algorithm"))*.
