第十章 将随机加权法首次应用到简单随机抽样方案下的样本均值分布逼近问题中，从数字特征角度说明了随机加权方法在抽样理论中的可用性，从而拓广了随机加权法的应用范围。

The shortest path approximation algorithm builds a weighted graph from the given set of scattered points using the distribution of these data points. By computing the shortest path in the weighted graph, the problem of curve reconstruction from scattered data points is transformed into that of curve reconstruction from a set of ordered data points.
