Perhaps you should try some spelling variations:
"element sampling algorithm" » "element mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search), "element mapping algorithm" (Expand Search), "client sampling algorithm" (Expand Search)
"elemental new algorithm" » "elemental xrd algorithm" (Expand Search), "elemental novel algorithm" (Expand Search), "elemental _ algorithm" (Expand Search)
"elements pso algorithm" » "elements two algorithms" (Expand Search), "elements _ algorithm" (Expand Search), "elements em algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements upon 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: (((("elemental new algorithm") OR ("elements pso algorithm"))) OR ("element sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elemental new algorithm\") OR (\"elements pso algorithm\"))) OR (\"element sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elemental new algorithm ) OR ( elements pso algorithm ))) OR ( element sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elemental new algorithm") OR ("elements pso algorithm"))) OR ("element sampling algorithm"))*.
