I recently learned about the particle effect in cocos2d. Let's share what I learned with you!
Now! Let's first understand the class structure.

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

The hybrid particle swarm optimization algorithm combines the global particle swarm algorithm with the local particle swarm algorithm, and its speed is updated using the formula
where G (k+1) is the global version of the speed update formula, and L (k+1) is a local version of the speed update formula, the hybrid particle
InIn the global standard particle swarm algorithm, the speed update of each particle changes according to two factors. The two factors are: 1. The historical optimal pI of the particle. 2. Global Optimal pg for particle populations. If you change the particle velocity update
The realization of the standard particle swarm optimization (PSO) algorithm is based on the particle Swarm algorithm (2)----the standard particle swarm optimization algorithm. It is mainly divided into 3 functions. The first function is the particle swarm initialization function

1. Examples
First, we'll start with a plane.
var entity = Viewer.entities.add ({
model: {
uri: ' ... /APPS/SAMPLEDATA/MODELS/CESIUMAIR/CESIUM_AIR.GLTF ',

},
position: Cesium.Cartesian3.fromDegrees ( -112.110693, 36.0994841, 1000.0)
});
Viewer.trackedentity = entity;
then we need to get to the plane's model position.

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
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

Particle swarm algorithm (particle SWARMOPTIMIZATION,PSO) proposed by Kennedy and Eberhart in 1995, the algorithm simulates the behavior of bird colony flying foraging, and the group achieves the optimal goal through collective collaboration, which is based on the swarm Optimization method of intelligence. Similar to the genetic algorithm, but also a group based on the iteration, but there is no genetic alg

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).
