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 method algorithms" » "element two algorithms" (Expand Search), "element both algorithms" (Expand Search), "element other algorithms" (Expand Search)
"element art algorithms" » "element ml algorithms" (Expand Search), "element _ algorithms" (Expand Search), "element based algorithms" (Expand Search), "element ore algorithms" (Expand Search), "element data 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: (("client sampling algorithm") OR ((("element method algorithms") OR ("element art algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"client sampling algorithm\") OR (((\"element method algorithms\") OR (\"element art algorithms\"))))".
• Removing quotes may allow a broader search: (( client sampling algorithm ) OR ((( element method algorithms ) OR ( element art algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("client sampling algorithm") OR ((("element method algorithms") OR ("element art algorithms"))))*.
