Respected Sir/Madam,
I am trying to implement PSO algorithm for capacitated vehicle routing problem and unable to get the idea how to intialize the particles?

I would suggest you to implement this function into your vehicle routing internal system in case you use any in your company. If you don`t, then developing a custom vehicle routing software would be an excellent solution to all types of vehicle routing problems. The benefit of custom development is that this solution will provide the functions that your company requires, including PSO algorithm.

Go through the following video tutorial, it has implementation of Particle Swarm Optimization (PSO). In the first part, theoretical foundations of PSO is briefly reviewed. In the next two parts of this video tutorial, PSO is implemented line-by-line and from scratch, and every line of code is described in detail. Maybe this will give you fair idea about the initialization of particle.
Hope, this helps.

To initialize the particles, just generate some random solution vectors

Hello, How to do the optimization with the PSO when we have an objective function which depends on two variables but the limits of variation of the two variables are different? for example -5 <x1 <3 and -100 <x2 <200

For CVRP, each particle can be initialized as a random solution to the problem, where each particle represents a different set of routes for the vehicles. It is recommended to experiment with different initialization methods and parameters to find the best solution for your specific problem.
