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