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)
"element mapping algorithm" » "element making algorithm" (Expand Search), "element mining algorithm" (Expand Search), "element learning algorithm" (Expand Search), "elemental mapping algorithm" (Expand Search), "element modeling algorithm" (Expand Search), "argument mapping algorithm" (Expand Search)
"element ml algorithms" » "element _ algorithms" (Expand Search), "element g algorithms" (Expand Search), "element te algorithms" (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 ml algorithms") OR ((("element mapping algorithm") OR ("client sampling algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"element ml algorithms\") OR (((\"element mapping algorithm\") OR (\"client sampling algorithm\"))))".
• Removing quotes may allow a broader search: (( element ml algorithms ) OR ((( element mapping algorithm ) OR ( client sampling algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("element ml algorithms") OR ((("element mapping algorithm") OR ("client sampling algorithm"))))*.
