  Nature-inspired algorithms such as Particle Swarm Optimization and Firefly
Algorithm are among the most powerful algorithms for optimization. In this
paper, we intend to formulate a new metaheuristic algorithm by combining Levy
flights with the search strategy via the Firefly Algorithm. Numerical studies
and results suggest that the proposed Levy-flight firefly algorithm is superior
to existing metaheuristic algorithms. Finally implications for further research
and wider applications will be discussed.
