Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"elements present algorithm" » "elements presented algorithm" (Expand Search), "elements treatment algorithm" (Expand Search), "elements forest algorithm" (Expand Search)
"element two algorithms" » "element _ algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element art algorithms" (Expand Search), "element te algorithms" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("elements present algorithm") OR ("element two algorithms"))) OR ("client sampling algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elements present algorithm\") OR (\"element two algorithms\"))) OR (\"client sampling algorithm\"))".
• Removing quotes may allow a broader search: (((( elements present algorithm ) OR ( element two algorithms ))) OR ( client sampling algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("elements present algorithm") OR ("element two algorithms"))) OR ("client sampling algorithm"))*.
