Abstract

The invention provides a multi-parameter optimization method. With the multi-parameter optimization method adopted, learning efficiency can be improved, and time complexity and space complexity can be decreased. The method includes the following steps that: the position and the number of iterations of each particle in a particle population are initialized, each dimension of the particle is corresponding to a parameter to be solved; the historical optimal position of each particle and the optimal position of the population are updated according to the calculated fitness value of each particle to an objective function, and an orthogonal algorithm is utilized to perform orthogonal calculation on the historical optimal position of each particle and the optimal position of the population, so that the learning vector of each particle can be obtained, the locations of particles of a next generation are determined according to the position and learning vector of each particle; and if reverse learning is performed, each particle is reversed, so that reverse particles can be obtained, if the fitness value of the reverse particles to the objective function is larger than the fitness value of the original particles to the objective function, the reverse particles are adopted to replace the original particles. The multi-parameter optimization method of the invention is applicable to the industrial parameter optimization technical field.
