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