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