Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element learning algorithm" » "element learning algorithms" (Expand Search), "excellent learning algorithm" (Expand Search), "student learning algorithm" (Expand Search), "agent learning 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)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("elements pso algorithm") OR ((("client sampling algorithm") OR ("element learning algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elements pso algorithm\") OR (((\"client sampling algorithm\") OR (\"element learning algorithm\"))))".
• Removing quotes may allow a broader search: (( elements pso algorithm ) OR ((( client sampling algorithm ) OR ( element learning algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("elements pso algorithm") OR ((("client sampling algorithm") OR ("element learning algorithm"))))*.
