Abstract: For some optimization problems in which there are many independent variables, the typical optimization algorithm cannot be used, or it would take the computer quite a long time to work them out. However, usually the optimum solution is not required in practical engineering, only a good, satisfactory solution being sufficient for it. In line with the peculiarities of certain practical engineering problems, the algorithm to solve a satisfactory solution can be found, which proves, to be a very efficient method.
On the basis of the characteristics of turbine blades mounted on every stage of a rotator, a practical algorithm for assembling blades is introduced in this paper According to this algorithm, the resultant moment of the wheel will be very small so long as some pairs of the right and left blades are exchanged and some pairs of high and low blades are also exchanged. The algorithm can be easily programmed and worked out on a microcomputer.
