Optimization Code for PSO Strategy

This is an integrated code used to perform the Particle Swarm Optimisation (PSO) for the dome roof frame. The model has three types of design variables: sizing, shape and topology. It can be used for any example just by accommodating the position vector to be fit with the vector defined in this code. The cost function could be defined as fraction of structural weight. in some cases, the cost function might be defined as stiffness objective, buckling, or stress function. The program has prepared to read the optimisation data for each stage from the pool of data available in the written .csv files. The code also has a section for plotting the design history of cost function. It also uses a customised functions to create the typologies of the optimal designs.
