Perhaps you should try some spelling variations:
"client sampling algorithm" » "client mining algorithm" (Expand Search), "sediment sampling algorithm" (Expand Search)
"element mapping algorithm" » "element matching algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search)
"element art algorithms" » "element _ algorithms" (Expand Search), "element ml algorithms" (Expand Search), "element based algorithms" (Expand Search), "element ore algorithms" (Expand Search), "element data 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: (((("element mapping algorithm") OR ("client sampling algorithm"))) OR ("element art algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element mapping algorithm\") OR (\"client sampling algorithm\"))) OR (\"element art algorithms\"))".
• Removing quotes may allow a broader search: (((( element mapping algorithm ) OR ( client sampling algorithm ))) OR ( element art algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("element mapping algorithm") OR ("client sampling algorithm"))) OR ("element art algorithms"))*.
