Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element five algorithms" » "element four algorithms" (Expand Search), "element based algorithms" (Expand Search), "element three algorithms" (Expand Search), "element fbe algorithms" (Expand Search), "element citre algorithms" (Expand Search), "element te algorithms" (Expand Search)
"element study algorithm" » "present study algorithm" (Expand Search), "recent study algorithm" (Expand Search), "event 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: (((("element five algorithms") OR ("element study algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element five algorithms\") OR (\"element study algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element five algorithms ) OR ( element study algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element five algorithms") OR ("element study algorithm"))) OR ("client sampling algorithm"))*.
