How to integrate PSO with BFS to minimize power loss in radial distribution system for network reconfiguration

Now I have some clue how I can integrate PSO algorizim with Back ward forward sweep method to minimize power loss by network reconfiguration.

But I want full MATLAB CODE of PSO by using BFS method to minimize power loss in my network reconfiguration. My project has 78 bus, 5 tie switchs and it is radial. so the out put will be

1.Active power loss before and after reconfiguration

2.Reactive power loss before and after reconfiguration

3. Voltage magnitude (p.u) before and after reconfiguration

4. voltage profile ( plot voltage) before and after reconfiguration,

5. Tie switch before and after reconfiguration. ( base case testing tie switch is 78,79,80,81 and 82)
