Particle swarm optimization (2)----standard particle swarm optimization algorithm

In the narrative of the previous section, the only thing that hasn't been introduced is how the random dots (particles) of a function are moving, only that they are updated according to a certain formula. This formula is the position Velocity update formula in the particle swarm algorithm. Here's what this formula is about. In the previous section we evaluated the [0,4] maximum value of the function Y=1-cos (3*x) *exp (-X). Two random points are place

Standard particle swarm optimization (particle Swarm optimization, PSO) algorithm

Let's start with the chatter. What is the optimization problem, is to meet certain constraints, to find a set of appropriate parameters, so that some of the system performance indicators (Optimality measures) to reach the maximum value. The iteration provides a basic idea for solving the optimization problem: \[\left\{\begin{gathered} A + b + x = 3y \hfill \ \ ax-by = 1 \hfill \ \ AB + xy = 2 \hfill \ \ A + b = {(x + y) ^2} \hfill \ \ \end{gathered} \right.\] Stand

question of the Byzantine general Four generals discuss the timing of the attack on Byzantium, in which any three of them can agree and win. As a result of their lack of mutual trust, they could not be in the same room and could only express their views to other generals through correspondence, for example, in the first round of communication, there could be 4 generals. So, how to coordinate, let everybody's attack time coincide. In such a case, if 40 people, or more people, how to coordinate i
