Perhaps you should try some spelling variations:
"element sampling algorithm" » "element making algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "element matching algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "client sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search)
"client mining algorithm" » "client finding algorithm" (Expand Search), "client making algorithm" (Expand Search), "client training algorithms" (Expand Search)
"elements small algorithm" » "elements all algorithms" (Expand Search), "elements swarm algorithm" (Expand Search), "elements mlm 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 sampling algorithm") OR ("elements small algorithm"))) OR ("client mining algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element sampling algorithm\") OR (\"elements small algorithm\"))) OR (\"client mining algorithm\"))".
• Removing quotes may allow a broader search: (((( element sampling algorithm ) OR ( elements small algorithm ))) OR ( client mining algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element sampling algorithm") OR ("elements small algorithm"))) OR ("client mining algorithm"))*.
