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

Deep understanding of Blockchain six: Bitcoin blockchain __ Blockchain

Blockchain Introduction A blockchain is a data structure that is logically linked from the back to the block that contains the transaction information. It can be stored as flat file, which contains files with no relative relational records, or stored in a simple database. Bitcoin core clients use Google's LEVELDB database to store blockchain metadata. Chunks are

Implementation of particle swarm optimization (8)---hybrid particle swarm optimization algorithm

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 s

Particle swarm algorithm (3)-standard particle swarm algorithm (local version)

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 formula, update the velocity of each particle based on the following two factors: a. The particle's own historical optimal pi. B. ParticlesNeighborhoodThe optimal PNK value of the
