Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"elements fusion algorithm" » "elements upon 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 ree algorithm" (Expand Search), "elements fe 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 fusion algorithm") OR ("elements uce algorithm"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements fusion algorithm\") OR (\"elements uce algorithm\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements fusion algorithm ) OR ( elements uce algorithm ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements fusion algorithm") OR ("elements uce algorithm"))) OR ("client sampling algorithm"))*.
