pso（ Population based stochastic optimization algorithm ）_ Baidu Encyclopedia

Yes pso make a concrete analysis ：

（1） initialization

Randomly generate particle swarm in the problem search space .

Particle related parameters ： velocity vector , Position vector , Fitness ;

（2） Optimal solution

Fitness calculation function fitness

（？ How exactly ）

（3） to update  

 

（4） loop 、 End

When the predefined fitness value is obtained or the maximum number of iterations is met .
