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 based algorithms" » "element based algorithm" (Expand Search), "engagement based algorithms" (Expand Search)
"element data algorithm" » "element data algorithms" (Expand Search), "element update algorithm" (Expand Search), "element atlas algorithm" (Expand Search), "settlement data algorithm" (Expand Search), "relevant data algorithm" (Expand Search), "movement data 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 data algorithm") OR ("element based algorithms"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"client sampling algorithm\") OR (((\"element data algorithm\") OR (\"element based algorithms\"))))".
• Removing quotes may allow a broader search: (( client sampling algorithm ) OR ((( element data algorithm ) OR ( element based algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("client sampling algorithm") OR ((("element data algorithm") OR ("element based algorithms"))))*.
