I. Basic CONCEPTS
Particle swarm optimization (particleswarm optimization,pso), a branch of evolutionary computing, is a stochastic search algorithm simulating biological activity in nature, and it is widely used in various engineering optimization problems to find the optimal solution through cooperative mechanism in the group.

A history of particle swarm optimization
Particle swarm optimization (Complex Adaptive system,cas) is derived from the complex adaptive system. CAS theory was formally introduced in 1994, and CAS members are called principals. For example, the study of bird systems, in which each bird is called the subject. The subject is adaptable, it can communicate with the environment and other subjects, and change its

Introduction to particle swarm algorithms
I. History of particle swarm algorithms
Particle swarm algorithms are derived from complex adaptive systems (CAS ). CAS theory was formally proposed in 1994. Members in CAs are called subjects. For example, to study a bird group system, every bird is called a subject in this system. The subject is adaptive. It can communi
Before we have deployed a Docker swarm cluster environment, we will briefly introduce the management of the swarm cluster.
Cluster scheduling strategy
Since it is a cluster, there is a scheduling policy, that is, the cluster contains so many sub-nodes, I exactly set a strategy to allocate it.
We look at the official Docker documentation to see that Swarm's cluster sch

Recently, we have to write an article about the particle swarm algorithm, so we have to implement the local version of PSO algorithm. The realization idea of the local version of particle swarm algorithm has already been described in the particle Swarm algorithm (3)----standard particle swarm algorithm (local version).
Particle swarm algorithm is mainly divided into 4 large branches:

First, the history of particle swarm algorithm
Particle swarm algorithm originates from complex adaptive system (Complex adaptive System,cas). CAS theory was formally proposed in 1994, and members in CAs are called principals. For example, the study of bird systems, each bird in this system is called the subject. Subject has adaptability, it can communicate with environment and other subject, and change it

Swarm is a Docker company launched to manage docker clusters. It turns a group of Docker hosts into a single, virtual host. Swarm uses standard Docker API interfaces as its front-end access portals. in other words, various forms of Docker clients (such as docker
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: \[\left\{\begin{gathered}
A + b + x = 3y \hfill \ \
ax-by = 1 \hfill \ \
AB + xy = 2 \hfill \ \
A + b = {(x + y) ^2} \hfill \ \
\end{gathered} \right.\]
