A Comprehensive Survey on Particle Swarm Optimization Algorithm and Its Applications

Table 3

Adherence to SI principles.

Principle	Adherence of PSO
Proximity principle	Particle swarm carried out N-dimensional space calculation over a series of time steps.
Quality principle	Particle swarm responds to quality factors pbest & gbest.
Diverse response principle	Particle swarm responses allocated between pbest and gbest.
Stability principle	Particle swarm changes state only when gbest changes.
Adaptability principle	Particle swarm changes state every time gbest changes.
