The vendor has the advantage of knowing his/her cost, so it helps a lot if you know theapproximate local market value.
所以,大概的了解一下当地的市场行情对于你的讲价是否成功是有很大帮助的。

An approximate minimizer ofcost function is found by using matching pursuit algorithm, and the filters are selected.
利用匹配追踪算法找到了一个近似最小的代价函数,从而选出了滤波器。

However you can raise the sample size to 10 at thecostof some additional CPU usage in order to closely approximate true LRU, and check if this makes a difference in your cache misses rate.
