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