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