很好 我采用得是串行方式对bp网络进行训练，为何训练时误差dsum约来越大？？望指教！(good, I have used in serial mode is the right bp network training, training errors are about to dsum greater? ? Look weekend!)

球赛门票的售票处规定每位购票者限购一张门票，且每张门票售价 50元。购票者中有 m位手持50元钱币，另有n人手持100元。假设售票处开始售票时无零钱。问这m+n人有 几种排队方式可使售票处不致出现找不出钱的局面。(The box office ticket sales are limited to the provisions of each ticket purchase a ticket, and the price of 50 yuan per ticket. Ticket-holders have m-bit hand-held 50 coins, and another n armed with 100 yuan. Suppose no small change when the ticket office began selling tickets. M+ n asking a few people queuing up outside ticket office can not find the money to avoid a situation.)

说明：  潮流计算是电力学名词，指在给定电力系统网络拓扑、元件参数和发电、负荷参量条件下，计算有功功率、无功功率及电压在电力网中的分布。潮流计算是根据给定的电网结构、参数和发电机、负荷等元件的运行条件，确定电力系统各部分稳态运行状态参数的计算。通常给定的运行条件有系统中各电源和负荷点的功率、枢纽点电压、平衡点的电压和相位角。待求的运行状态参量包括电网各母线节点的电压幅值和相角，以及各支路的功率分布、网络的功率损耗等。(Power flow calculation is a term of power science. It refers to the calculation of the distribution of active power, reactive power and voltage in power network under given network topology, component parameters and generation and load parameters. Power flow calculation is based on the given grid structure, parameters and operation conditions of generator, load and other components to determine the steady-state operation parameters of each part of the power system. Usually, the given operating conditions include the power of each power source and load point, junction voltage, balance point voltage and phase angle. The parameters to be determined include the voltage amplitude and phase angle of each bus node, the power distribution of each branch and the power loss of the network.)
