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)
"elements uce algorithm" » "elements each algorithm" (Expand Search), "elements cc3d algorithm" (Expand Search), "elements ipca algorithm" (Expand Search), "elements ices algorithm" (Expand Search), "elements fe algorithm" (Expand Search), "elements ree algorithm" (Expand Search)
"element gnb algorithm" » "element mnb algorithm" (Expand Search), "element anbs algorithm" (Expand Search), "element cnn algorithm" (Expand Search), "element g 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: (((("elements uce algorithm") OR ("element gnb algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements uce algorithm\") OR (\"element gnb algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements uce algorithm ) OR ( element gnb algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements uce algorithm") OR ("element gnb algorithm"))) OR ("client sampling algorithm"))*.
