Perhaps you should try some spelling variations:
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client mining algorithm" (Expand Search)
"element mean algorithm" » "element means algorithm" (Expand Search), "element new algorithm" (Expand Search), "element each algorithm" (Expand Search), "element mesh algorithm" (Expand Search), "latent mean algorithm" (Expand Search), "element te algorithm" (Expand Search)
"elements b algorithm" » "elements _ algorithm" (Expand Search), "elements box algorithm" (Expand Search), "elements dbo algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element g 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: (((("element mean algorithm") OR ("elements b algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mean algorithm\") OR (\"elements b algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element mean algorithm ) OR ( elements b algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element mean algorithm") OR ("elements b algorithm"))) OR ("client sampling algorithm"))*.
