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