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 three algorithms" » "element forest algorithms" (Expand Search), "element based algorithms" (Expand Search), "element art algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (Expand Search)
"element five algorithms" » "element four algorithms" (Expand Search), "element forest algorithms" (Expand Search), "element based algorithms" (Expand Search), "element fbe algorithms" (Expand Search), "element citre algorithms" (Expand Search), "element te algorithms" (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 three algorithms") OR ("element five algorithms"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element three algorithms\") OR (\"element five algorithms\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( element three algorithms ) OR ( element five algorithms ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element three algorithms") OR ("element five algorithms"))) OR ("client sampling algorithm"))*.
