Perhaps you should try some spelling variations:
"client mining algorithm" » "client finding algorithm" (Expand Search), "client making algorithm" (Expand Search), "client training algorithms" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element art algorithms" (Expand Search), "element two algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "element ore algorithms" (Expand Search)
"element rf algorithm" » "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search), "element art algorithms" (Expand Search), "element ore algorithm" (Expand Search), "element ree algorithm" (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: (("client mining algorithm") OR ((("element tree algorithms") OR ("element rf algorithm"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"client mining algorithm\") OR (((\"element tree algorithms\") OR (\"element rf algorithm\"))))".
• Removing quotes may allow a broader search: (( client mining algorithm ) OR ((( element tree algorithms ) OR ( element rf algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("client mining algorithm") OR ((("element tree algorithms") OR ("element rf algorithm"))))*.
