Perhaps you should try some spelling variations:
"present within algorithm" » "present switching algorithm" (Expand Search), "present matching algorithm" (Expand Search), "present twisting algorithm" (Expand Search)
"client mining algorithm" » "client learning algorithm" (Expand Search), "client means algorithm" (Expand Search)
"client sampling algorithm" » "sediment sampling algorithm" (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: (("present within algorithm") OR ((("client sampling algorithm") OR ("client mining algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"present within algorithm\") OR (((\"client sampling algorithm\") OR (\"client mining algorithm\"))))*".
• Removing quotes may allow a broader search: (( present within algorithm ) OR ((( client sampling algorithm ) OR ( client mining algorithm ))))*.
