Perhaps you should try some spelling variations:
"client samplingnb algorithm" » "client sampling algorithm" (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)
"element g algorithm" » "element _ algorithm" (Expand Search), "element b algorithm" (Expand Search), "element gnb algorithm" (Expand Search), "elements _ 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 g algorithm") OR ("element data algorithm"))) OR ("client samplingnb algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element g algorithm\") OR (\"element data algorithm\"))) OR (\"client samplingnb algorithm\"))".
• Removing quotes may allow a broader search: (((( element g algorithm ) OR ( element data algorithm ))) OR ( client samplingnb algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element g algorithm") OR ("element data algorithm"))) OR ("client samplingnb algorithm"))*.
