Optimization using Particle swarm optimization

Hi Everyone, I have two variables for optimization. x1 = (10,20,30,40,50), x2 = (5,10,15,20,25). Both variables optimum value using Particle swarm optimization (PSO) should be choose from given values above. So i did not understand how to do it with PSO. As both variables have fixed values and optimum value of each variable should be chosen from above values of x1 and x2 by PSO. There is no upper bond and lower bond for PSO. Anyone can help me or guide me to implement it in matlab. Is there any function available in matlab to do it.

Hi,

I understand that you have an objective function whose value is dependent on “x1” and “x2” and you want to find the optimal value of the function using PSO.

Since you want to find optimal value from a specific set of values of “x1” and “x2”, you could try all the combinations of “x1” and "x2" to get the optimal value and corresponding values of “x1” and “x2”. You can refer the below link to get to know more about discrete integer function optimization.

Hi Aman, Thank you for answer. I see the link and he mentioned that he did it for PSO. But didn't share any help detail which can help me to solve my problem.
