此程序从国外网站收集得到，是标准的深度优先搜索算法，可实现节点遍历和检测回路的功能，详细情况请看原英文注释 我在此程序中添加了随机性，即遇到分叉时，随机选下一个节点，成为随机深度优先搜索算法-This procedure has been collected from the foreign website, the standard depth-first search algorithm, can be achieved and the detection circuit node t

Assume three-phase voltages at the end nodes (6,8,9,11, and 13). The usual assumption is to use the nominal voltages. 2. Starting at Node 13, compute the node current (load current plusoke
