Firefly Algorithm (FA) mimics the flashing light characteristic of fireflies to solve optimization problems. An area where its utilization is limited is Travelling Salesman Problem (TSP). There are a number of algorithms utilized to solve the problem; however. there is still scope to do better in terms of solution quality. https://www.chiggate.com/five-finger-death-punch-a-decade-of-destruction-vol-1-cd-supply/
