【Abstract】 Several methods have been tried to simplify programming and enhance the calculating efficiency of gene~tic algorithms (G As), which are used in least cost network analysis. They are chromosome vectors coded by floating point numbers using commercial series of pipe diameters, introducing initial solutions, using dynamic fitness function and keeping the best individual. The validity of these methods is confirmed by comparing with literature.更多还原
