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