Perhaps you should try some spelling variations:
"client sampling algorithm" » "client making algorithm" (Expand Search), "client modeling algorithm" (Expand Search), "client matching algorithm" (Expand Search)
"client mining algorithm" » "client finding algorithm" (Expand Search), "client making algorithm" (Expand Search), "client training algorithms" (Expand Search)
"event study algorithm" » "event wsindy algorithm" (Expand Search), "event td3 algorithm" (Expand Search), "event seu algorithm" (Expand Search), "recent study algorithm" (Expand Search), "present study 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: (((("event study algorithm") OR ("client sampling algorithm"))) OR ("client mining algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"event study algorithm\") OR (\"client sampling algorithm\"))) OR (\"client mining algorithm\"))".
• Removing quotes may allow a broader search: (((( event study algorithm ) OR ( client sampling algorithm ))) OR ( client mining algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("event study algorithm") OR ("client sampling algorithm"))) OR ("client mining algorithm"))*.
