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 mesh algorithm" » "element best algorithm" (Expand Search), "element mean algorithm" (Expand Search), "element means algorithm" (Expand Search), "element method algorithm" (Expand Search), "elements mges algorithm" (Expand Search), "element te algorithm" (Expand Search)
"element td3 algorithm" » "element cc3d algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element te algorithm" (Expand Search), "element study 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: (("client sampling algorithm") OR ((("element mesh algorithm") OR ("element td3 algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"client sampling algorithm\") OR (((\"element mesh algorithm\") OR (\"element td3 algorithm\"))))".
• Removing quotes may allow a broader search: (( client sampling algorithm ) OR ((( element mesh algorithm ) OR ( element td3 algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("client sampling algorithm") OR ((("element mesh algorithm") OR ("element td3 algorithm"))))*.
