Perhaps you should try some spelling variations:
"recent mining algorithm" » "recent learning algorithm" (Expand Search), "recent means algorithm" (Expand Search), "recent finding algorithm" (Expand Search), "recent findings algorithm" (Expand Search)
"client sampling algorithm" » "sediment sampling algorithm" (Expand Search)
"element tree algorithms" » "element three algorithms" (Expand Search), "element other algorithms" (Expand Search), "element art algorithms" (Expand Search), "element ree algorithms" (Expand Search), "element te algorithms" (Expand Search), "elements ree algorithms" (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 sampling algorithm") OR ("recent mining algorithm"))) OR ("element tree algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"client sampling algorithm\") OR (\"recent mining algorithm\"))) OR (\"element tree algorithms\"))".
• Removing quotes may allow a broader search: (((( client sampling algorithm ) OR ( recent mining algorithm ))) OR ( element tree algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("client sampling algorithm") OR ("recent mining algorithm"))) OR ("element tree algorithms"))*.
