Size Optimization of Truss Structure using Particle Swarm Optimization

Particle Swarm Optimization is one of a meta-heuristic algorithm which was used in many real world optimization problems of many fields including civil engineering field as well. Particle Swarm Optimization was first introduced by Kennedy and Eberhart in 1995. The algorithm was proposed based on the behavior or movement of a bird flock.
To apply the theory of PSO to the optimization problem, we can implement the theory to Python code to do the size optimization of truss structure.
In the video below, we can find the minimum total weight of truss structure by using the PSO algorithm with Python programming language.
