Perhaps you should try some spelling variations:
"client samplin_ algorithm" » "client sampling algorithm" (Expand Search)
"element method algorithm" » "element network algorithm" (Expand Search), "element means algorithm" (Expand Search), "element mean algorithm" (Expand Search)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ 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 g algorithm") OR ("element method algorithm"))) OR ("client samplin_ algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element g algorithm\") OR (\"element method algorithm\"))) OR (\"client samplin_ algorithm\"))".
• Removing quotes may allow a broader search: (((( element g algorithm ) OR ( element method algorithm ))) OR ( client samplin_ algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element g algorithm") OR ("element method algorithm"))) OR ("client samplin_ algorithm"))*.
