Abstract

The invention relates to a chaotic particle swarm algorithm based on a discussion mechanism. The chaotic theory is used to initialize the population, so that the initial particles are uniformly distributed in the space, and the chaotic ergodicity is used for searching to make the algorithm jump out of the local optimum. The chaotic particle swarm algorithm is directed to the problem of low convergence accuracy of the existing algorithm, uses dual populations, and combines the discussion mechanism to enhance the convergence accuracy.

Description

technical field [0001] The invention relates to the field of particle swarm algorithm design, in particular to a chaotic particle swarm algorithm based on discussion mechanism. Background technique [0002] In 1995, J.Kennedy and R.C.Eberhart first proposed the particle swarm optimization algorithm (PSO) at the IEEE International Conference. Particle swarm optimization algorithm is a bionic swarm intelligence algorithm. By simulating some characteristics of birds looking for food, a global random search algorithm is proposed. [0003] The particle swarm optimization algorithm has a fast convergence speed, and the setting of parameter variables is simple and convenient. It once became a hot spot for many researchers to study and apply, and it is used to solve theoretical problems such as parameter optimization, neural network, pattern recognition, and engineering problems such as equipment monitoring, power system, and industrial control. The particle swarm optimization alg...
