Optimization in the face of nearly ordered array Compare to MergeSort, the Sorting Tree generate by Quick Sort is more unbalanced.The worst situation the effience of quick sort can be deteriorate to $O(n^2)$ Tradinational Method using the left element to be demarcating element. In order to...
The B-tree and its variants are useful to index and search data inone-dimensional space(where data is stored on disks rather than main memory). The basic idea is to separate a line into several segments and gradually reduce to the minimum segment where the searched data is located, illustrat...

我科研里面主要用的是stochastic boosted decision tree,可以把这个model想象成一个box,每一个对撞event就是如下的一个data structure, 这里的variable指的是探测器里面测量的粒子的物理变量。这样这个model经过signal MC和background MC训练完之后,任意给其一个event(其内部有同样的variable,但不同的值)都可以给出一个...
