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