Schematic diagram of the basic principle of PSO, two moving particles 1 and 2 exist in two-dimensional space. Under the joint action of p_best and , both particles deviate from the original direction of motion and turn to the direction of the best position. In this way the example gets rid of the original local optimal position and gradually converges to the global optimal position.
