【Abstract】 Use of genetic algorithm to optimize the design for medium- and large-scale sewer network in combination with the node recursive algorithm is presented. The method can satisfy the requirement for joining hydraulically the nodes within the network, and achieve the overall optimization of the network. Genetic algorithm needs only the objective function values and needs not the derivatives, and can optimize the hydraulic parameters of the whole network, so as to attain the target with the lowest cost. The operating parameters of genetic algorithm are determined based on the optimization design of medium-scale sewer network.更多还原
