Eagle Strategy Using Lévy Walk and Firefly Algorithms for Stochastic Optimization

Most global optimization problems are nonlinear and thus difficult to solve, and they become even more challenging when uncertainties are present in objective functions and constraints. This paper provides a new two-stage hybrid search method, called Eagle Strategy, for stochastic optimization. This strategy intends to combine the random search using L´evy walk with the firefly algorithm in an iterative manner. Numerical studies and results suggest that the proposed Eagle Strategy is very efficient for stochas- tic optimization. Finally practical implications and potential topics for further research will be discussed.
