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